So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Frydrych, Jan; Slaveetinska, Lenka Postova; Draccinsky, Martin; Janeba, Zlatko researched the compound: 2-Bromomethyl-1,3-dioxolane( cas:4360-63-8 ).Application of 4360-63-8.They published the article 《Efficient synthesis of α-branched purine-based acyclic nucleosides: scopes and limitations of the method》 about this compound( cas:4360-63-8 ) in Molecules. Keywords: acyclonucleoside preparation; nitrogen heterocycle acetal anhydride alkylation; acyclonucleosides; hemiaminal ether; multi-component reaction; purine. We’ll tell you more about this compound (cas:4360-63-8).

An efficient route to acylated acyclic nucleosides containing a branched hemiaminal ether moiety was reported via three-component alkylation of N-heterocycle (purine nucleobase) with acetal (cyclic or acyclic, variously branched) and anhydride (preferentially acetic anhydride). The procedure employed cheap and easily available acetals, acetic anhydride, and trimethylsilyl trifluoromethanesulfonate (TMSOTf). The multi-component reaction was carried out in acetonitrile at room temperature for 15 min and provides moderate to high yields (up to 88%) of diverse acyclonucleosides branched at the aliphatic side chain. The procedure exhibited a broad substrate scope of N-heterocycles and acetals, and, in the case of purine derivatives, also excellent regioselectivity, giving almost exclusively N-9 isomers.

Author is El Rayes, Samir M.; Ali, Ibrahim A. I.; Fathalla, Walid; Mahmoud, Mostafa A. A..

Me 2-(4-oxobenzotriazin-3(4H)-yl)alkanoates I [X = CH2, CH2CH2, CH(i-Pr); X1 = MeO] proved to be important intermediates for the preparation of some biol. interesting compounds containing the benzotriazinone ring system. The above compounds were prepared by direct diazotization of Me anthranilate followed by addition of amino acid esters hydrochloride in a one-pot strategy. An equivocal synthesis of compound I (X = CH2; X1 = MeO) was achieved by alkylation of benzotriazin-4(3H)-one with Me chloroacetate. A series of N-alkyl-2-(4-oxobenzotriazin-3(4H)-yl) alkanamides I (X = CH2, CH2CH2; X1 = NR1R2; R1 = i-Pr, n-Bu, t-Bu, cyclohexyl, etc., R2 = H; R1R2N = 1-piperidinyl, 4-morpholinyl) and Me 2-(2-(4-oxobenzotriazin-3(4H)-yl)alkanamido)alkanoates (dipeptides) I [X = CH2, CH2CH2; X1 = NHR3; R3 = MeO2CCH2, MeO2CCH(i-Bu), MeO2C(CH2)3, MeO2CCH(indol-3-ylmethyl)] were prepared via azide coupling from compounds I (X = CH2, CH2CH2; X1 = MeO). Esters I (X = CH2, CH2CH2; X1 = MeO) were converted into the corresponding hydrazides followed by condensation with aldehydes, such as 4-methoxybenzaldehyde, 4-dimethylaminobenzaldehyde and arabinose, to afford the corresponding hydrazone derivatives. All the synthesized compounds were subjected to the mol. docking using MOE 2008-10 software as agonists for E. coli Fab-H receptor and Vitamin D receptor for antibacterial and anticancer evaluation, resp. The most pronounced strong binding affinity towards the target E. coli Fab-H receptor was shown by the parent benzotriazin-4(3H)-one and compounds I [X = CH2, X1 = i-PrNH; X = CH2CH2, X1 = MeO2CCH2, MeO2C(CH2)3; X = CH2, X1 = 4-MeOC6H4CH:NN, 4-Me2NC6H4CH:NN; X = CH2CH2, X1 = 4-Me2NC6H4CH:NN]. On the other hand, the most pronounced strong binding affinity towards the target Vitamin D receptor were benzotriazin-4(3H)-one and compounds I [X = CH2, X1 = MeO2C(CH2)3; X = CH2CH2, X1 = MeO2CCH(indol-3-ylmethyl); X = CH2, X1 = 4-MeOC6H4CH:NN]. The in-vitro antibacterial activity of highest binding affinity docked compounds were tested against E. coli, Staphylococcus aureus and Salmonella spp. All the tested compounds gave effective pos. results against E. coli with inhibitory zone of about 1.1 cm, while were inactive against Staphylococcus aureus and Salmonella spp. The in-vitro cytotoxic activity of the highest binding affinity docked compounds were tested against human liver carcinoma cell line (HepG2) cancer cell lines. Many compounds showed potent cytotoxic activity with low IC50 values, especially benzotriazin-4(3H)-one (6.525μM) and I (X = CH2; X1 = 4-MeOC6H4CH:NN) (10.97μM) compared to standard drug doxorubicin (5.8μM).

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide(SMILESS: CC1=CP(CC1)(C2=CC=CC=C2)=O,cas:707-61-9) is researched.Synthetic Route of C11H13OP. The article 《Part I: The Development of the Catalytic Wittig Reaction》 in relation to this compound, is published in Chemistry – A European Journal. Let’s take a look at the latest research on this compound (cas:707-61-9).

The authors have developed the first catalytic (in phosphane) Wittig reaction (CWR). The utilization of an organosilane was pivotal for success as it allowed for the chemoselective reduction of a phosphane oxide. Protocol optimization evaluated the phosphane oxide pre-catalyst structure, loading, organosilane, temperature, solvent, and base. These studies demonstrated that to maintain viable catalytic performance it was necessary to employ cyclic phosphane oxide pre-catalysts of type 1. Initial substrate studies utilized sodium carbonate as a base, and further experimentation identified N,N-diisopropylethylamine (DIPEA) as a soluble alternative. The use of DIPEA improved the ease of use, broadened the substrate scope and decreased the pre-catalyst loading. The optimized protocols were compatible with alkyl, aryl, and heterocyclic (furyl, indolyl, pyridyl, pyrrolyl, and thienyl) aldehydes to produce both disubstituted and trisubstituted olefins in moderate-to-high yields (60-96%) by using a pre-catalyst loading of 4-10 mol%. Kinetic E/Z selectivity was generally 66:34. Complete (E)-selectivity for disubstituted α,β-unsaturated products was achieved through a phosphane-mediated isomerization event. The CWR was applied to the synthesis of a known precursor to the anti-Alzheimer drug donepezil hydrochloride, on a multi-gram scale (12.2 g, 74% yield). In addition, the described CWR is the only transition-metal-free/heavy-metal-free catalytic olefination process, excluding proton-catalyzed elimination reactions. The synthesis of the target compounds was achieved (1R,3S)-rel-3-methyl-1-phenylphospholane 1-oxide, (1R,3R)-rel-3-methyl-1-phenylphospholane 1-oxide, 1-phenylphospholane 1-oxide as catalyst precursors. 2-Phenyl-1,3,2-dioxaphospholane 2-oxide, diethylphenylphosphine oxide, 5-phenyl-5H-benzo[b]phosphindole 5-oxide, (2R,2’R,5R,5’R)-1,1′-(1,2-ethanediyl)bis[2,5-bis(1-methylethyl)phospholane], 2-[2-[(2R,5R)-2,5-dimethyl-1-phospholanyl]phenyl]-1,3-dioxolane were also evaluated.
