An efficient electrophilic N-cyanation of amines e.g., pyrrolidine with a stable and less-toxic 1-cyano-1,2-benziodoxol-3-(1H)-one reagent towards the synthesis of cyanamides e.g., Pyrrolidine-1-carbonitrile was disclosed. This synthetically practicable strategy allows the construction of a wide variety of cyanamides under very mild and simple conditions with a broad functional group compatibility, and showcases a huge potential in late-stage modification of complex mols.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds.

We report a photochem. method for the chemoselective radical functionalization of tryptophan (Trp)-containing peptides. The method exploits the photoactivity of an electron donor-acceptor complex generated between the tryptophan unit and pyridinium salts. Irradiation with weak light (390 nm) generates radical intermediates right next to the targeted Trp amino acid, facilitating a proximity-driven radical functionalization. This protocol exhibits high chemoselectivity for Trp residues over other amino acids and tolerates biocompatible conditions.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 7524-52-9, is researched, SMILESS is N[C@@H](CC1=CNC2=CC=CC=C12)C(OC)=O.[H]Cl, Molecular C12H15ClN2O2Journal, Article, European Journal of Medicinal Chemistry called Discovery and preliminary mechanism of 1-carbamoyl β-carbolines as new antifungal candidates, Author is Sheng, Tao; Kong, Mengmeng; Wang, Yujie; Wu, HuiJun; Gu, Qin; Chuang, Anita Shyying; Li, Shengkun; Gao, Xuewen, the main research direction is carbamoyl carboline preparation antifungal activity docking study SAR; Action mechanism; Antifungal activities; Gaeumannomyces graminis; Histone acetylation; β-Carboline.COA of Formula: C12H15ClN2O2.

Various 1-substituted β-carbolines I (R1 = CH3, C6H5, 4-BrC6H4, etc.), II (R2 = C6H5, CONH2, CONHC6H5, etc.), III (R3 = Me, Ph, OH, etc.) and IV (R4 = Me, Ph, 2-pyridyl, etc.) were synthesized from com. inexpensive tryptophan and demonstrated significant in vitro antifungal activity against G. graminis. Significantly, compound II (R2 = CONH2) (EC50 = 0.45μM) with carboxamide at 1-position displayed the best efficacy and nearly 20 folds enhancement in antifungal potential compared to Silthiopham (EC50 = 8.95μM).

Ren, Yansong; Kravchenko, Oleksandr; Ramstroem, Olof published the article 《Configurational and Constitutional Dynamics of Enamine Molecular Switches》. Keywords: enamine mol switche configurational constitutional dynamic; constitutional; dynamic; enamine; responsive; switch.They researched the compound: H-Trp-OMe.HCl( cas:7524-52-9 ).Quality Control of H-Trp-OMe.HCl. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:7524-52-9) here.

Dual configurational and constitutional dynamics in systems based on enamine mol. switches has been systematically studied. pH-responsive moieties, such as 2-pyridyl and 2-quinolinyl units, were required on the “”stator”” part, also providing enamine stability through intramol. hydrogen-bonding (IMHB) effects. Upon protonation or deprotonation, forward and backward switching could be rapidly achieved. Extension of the stator π-system in the 2-quinolinyl derivative provided a higher E-isomeric equilibrium ratio under neutral conditions, pointing to a means to achieve quant. forward/backward isomerization processes. The “”rotor”” part of the enamine switches exhibited constitutional exchange ability with primary amines. Interestingly, considerably higher exchange rates were observed with amines containing ester groups, indicating potential stabilization of the transition state through IMHB. Acids, particularly BiIII, were found to efficiently catalyze the constitutional dynamic processes. In contrast, the enamine and the formed dynamic enamine system showed excellent stability under basic conditions. This coupled configurational and constitutional dynamics expands the scope of dynamic C-C and C-N bonds and potentiates further studies and applications in the fields of mol. machinery and systems chem.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of novel deoxy λ5 phospha sugar nucleosides: 1,3-dipolar cycloaddition of an azidophospholane with alkynes, published in 2001-12-07, which mentions a compound: 707-61-9, Name is 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, Molecular C11H13OP, Recommanded Product: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide.

Several novel phospha sugar nucleosides, analogs of normal sugar nucleosides, were synthesized from a phospholene 1-oxide derivative Bromination of a phospholene precursor in aqueous organic medium gave regio diastereomers, the threo and erythro bromohydrins (1-bromo-1,3,4-trideoxy-1,4-C-[(R,S)-phenylphosphinylidene]-glycero-tetrofuranose). Further substitution of the threo isomer with sodium azide led to its corresponding azidophospholane (1-azido-1,3,4-trideoxy-2-methyl-1,4-C-[(R)-phenylphosphinylidene]-β-D-glycero-tetrofuranose) (I). 1,3-Dipolar cycloaddition of I with various electron-deficient and electron-rich alkynes afforded triazole derivatives that are nucleoside analogs. The strong electron-withdrawing phosphoryl group in the hemiacetal ring exerted no effect over reaction regioselectivity of the 1,3-dipolar cycloaddition, but steric effects of the alkynes played a vital role on the selectivity, since the regioisomer ratios and the rates and yields of cycloadducts changed as the bulkiness of the substituents on the acetylene changes. Structures of all compounds were unequivocally confirmed by 1H, 13C, and 31P NMR and mass spectral studies. Single crystal X-ray crystallog. anal. of some derivatives allowed determination of configuration of the phospha sugar nucleosides.

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.
