Novel phosphorus heterocyclic compounds, 3-methyl-1-(3-bromophenyl as well as some 3-substituted phenyl)-2-phospholene 1-oxides, were synthesized from 1-phenyl-2-phospholene 1-oxide via 3-methyl-1-(3-nitrophenyl)-2-phospholene 1-oxide. 1-(4-Bromophenyl)-2-phospholene was prepared by Grignard coupling reaction of 1-chloro-3-methyl-2-phospholene 1-oxide with 4-bromophenylmagnesium bromide. 2,3-Dibromo-3-methyl-1-arylphospholane 1-oxides were prepared by the addition reaction of bromine to the C=C double bond of 2-phospholenes. The substituent effect of the Ph group of the 1-aryl-phospholanes on the observed anti-proliferative effect against U937 leukemia cell lines evaluated by MTT in vitro methods showed that 2,3-dibromo-3-methyl-1-(4-bromophenyl)phospholane was the most active among 1-arylphospholanes. These novel dibromophosphorus heterocyclic derivatives exhibit much higher anticancer activity than Gleevec (mol. targeting chemotherapeutic agent) against U937 cells.

Safety of H-Trp-OMe.HCl. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: H-Trp-OMe.HCl, is researched, Molecular C12H15ClN2O2, CAS is 7524-52-9, about Mild and Chemoselective Thioacylation of Amines Enabled by the Nucleophilic Activation of Elemental Sulfur. Author is Saito, Masato; Murakami, Sho; Nanjo, Takeshi; Kobayashi, Yusuke; Takemoto, Yoshiji.

A mild and chemoselective method for the thioacylation of amines using α-keto acids and elemental sulfur has been developed. The key to the success of this transformation is the nucleophilic activation of elemental sulfur by thiols such as 1-dodecanethiol. A variety of functional groups, including unprotected hydroxyl, carboxyl, amide, sulfide, and tertiary amine moieties, are tolerated under the applied reaction conditions. To demonstrate the advantages of this method compared with conventional O-S exchange reactions using Lawesson’s reagent or P2S5, thioamide moieties were introduced site-specifically into biol. active compounds

Formula: C11H8Br2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2-Bromo-6-(bromomethyl)naphthalene, is researched, Molecular C11H8Br2, CAS is 305798-02-1, about Investigation of the structural requirements for N-methyl-D-aspartate receptor positive and negative allosteric modulators based on 2-naphthoic acid. Author is Irvine, Mark W.; Fang, Guangyu; Sapkota, Kiran; Burnell, Erica S.; Volianskis, Arturas; Costa, Blaise M.; Culley, Georgia; Collingridge, Graham L.; Monaghan, Daniel T.; Jane, David E..

The N-methyl-D-aspartate receptor (NMDAR), a ligand-gated ion channel activated by L-glutamate and glycine, plays a major role in the synaptic plasticity underlying learning and memory. NMDARs are involved in neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease and NMDAR hypofunction is implicated in schizophrenia. Herein we describe structure-activity relationship (SAR) studies on 2-naphthoic acid derivatives to investigate structural requirements for pos. and neg. allosteric modulation of NMDARs. These studies identified compounds such as UBP684 (14b), which act as pan potentiators by enhancing NMDAR currents in diheteromeric NMDAR tetramers containing GluN1 and GluN2A-D subunits. 14B and derivatives thereof are useful tools to study synaptic function and have potential as leads for the development of drugs to treat schizophrenia and disorders that lead to a loss of cognitive function. In addition, SAR studies have identified a series of styryl substituted compounds with partial NAM activity and a preference for inhibition of GluN2D vs. the other GluN2 subunits. In particular, the 3-and 2-nitrostyryl derivatives UBP783 (79i) and UBP792 (79h) had IC50s of 1.4 μM and 2.9 μM, resp., for inhibition of GluN2D but showed only 70-80% maximal inhibition. GluN2D has been shown to play a role in excessive pain transmission due to nerve injury and potentially in neurodegenerative disorders. Partial GluN2D inhibitors may be leads for the development of drugs to treat these disorders without the adverse effects observed with full NMDAR antagonists.

HPLC of Formula: 1265884-98-7. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine, is researched, Molecular C34H22NO2P, CAS is 1265884-98-7, about Synergetic iridium and amine catalysis enables asymmetric [4+2] cycloadditions of vinyl aminoalcohols with carbonyls. Author is Zhang, Mao-Mao; Wang, Ya-Ni; Wang, Bao-Cheng; Chen, Xiao-Wang; Lu, Liang-Qiu; Xiao, Wen-Jing.

Catalytic asym. cycloadditions via transition-metal-containing dipolar intermediates are a powerful tool for synthesizing chiral heterocycles. However, within the field of palladium catalysis, compared with the well-developed normal electron-demand cycloadditions with electrophilic dipolarophiles, a general strategy for inverse electron-demand ones with nucleophilic dipolarophiles remains elusive, due to the inherent linear selectivity in the key palladium-catalyzed intermol. allylations. Herein, based on the switched regioselectivity of iridium-catalyzed allylations, two asym. [4+2] cycloadditions of vinyl aminoalcs. with aldehydes and β,γ-unsaturated ketones through synergetic iridium and amine catalysis were achieved. The activation of vinyl aminoalcs. by iridium catalysts and carbonyls by amine catalysts provide a foundation for the subsequent asym. [4+2] cycloadditions of the resulting iridium-containing 1,4-dipoles and (di)enamine dipolarophiles. The former provides a straightforward route to a diverse set of enantio-enriched hydroquinolines bearing chiral quaternary stereocenters, and the later represent an enantio- and diastereodivergent synthesis of chiral hydroquinolines.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine, is researched, Molecular C34H22NO2P, CAS is 1265884-98-7, about Iridium-Catalyzed Enantioselective Allylic Alkylation with Functionalized Organozinc Bromides.Related Products of 1265884-98-7.

Enabled by a chiral Ir/(P,olefin) complex, this method allows allylic substitution with various primary and secondary alkyl nucleophiles with excellent regio- and enantioselectivities. The developed reaction was showcased in a concise, asym. synthesis of (-)-preclamol.

Application of 1265884-98-7. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate.

Author is Petrone, David A.; Isomura, Mayuko; Franzoni, Ivan; Rossler, Simon L.; Carreira, Erick M..

An enantioconvergent C(sp3)-C(sp3) coupling between racemic allenylic electrophiles and alkylzinc reagents has been developed. An Ir/(phosphoramidite,olefin) catalyst provides access to highly enantioenriched allenylic substitution products (93-99% ee) with complete regiocontrol (>50:1 rr in all cases) over the undesired 1,3-dienes isomers which are obtained predominantly in the case of other metal catalysts. The synthetic utility of the products obtained was highlighted in a variety of stereoselective transition metal-catalyzed difunctionalization reactions. Furthermore, a combination of computational and exptl. studies supports a putative reaction mechanism wherein enantiodetermining C-C coupling occurs via nucleophilic attack on a highly planarized aryl butadienyl π-system that is coordinated to the Ir center in an η2-fashion.

D. functional theory calculations supported the idea that the accurate discrimination of two spiroindoline enantiomers by (η3-allyl)-iridium(III) species and the perfect central-to-axial chirality conversion during C-C bond fragmentation ensure the stereoselective formation of two contiguous stereogenic centers and one axis in the medium-sized lactams.

This literature about this compound(1265884-98-7)Name: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepinehas given us a lot of inspiration, and I hope that the research on this compound(5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine) can be further advanced. Maybe we can get more compounds in a similar way.
