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.Mas-Rosello, Josep; Smejkal, Tomas; Cramer, Nicolai researched the compound: 2-Bromomethyl-1,3-dioxolane( cas:4360-63-8 ).HPLC of Formula: 4360-63-8.They published the article 《Iridium-catalyzed acid-assisted asymmetric hydrogenation of oximes to hydroxylamines》 about this compound( cas:4360-63-8 ) in Science (Washington, DC, United States). Keywords: iridium catalyzed acid assisted asym hydrogenation oxime hydroxylamine. We’ll tell you more about this compound (cas:4360-63-8).

Asym. hydrogenations are among the most practical methods for the synthesis of chiral building blocks at industrial scale. The selective reduction of an oxime to the corresponding chiral hydroxylamine derivative remains a challenging variant because of undesired cleavage of the weak nitrogen-oxygen bond. We report a robust cyclometalated iridium(III) complex bearing a chiral cyclopentadienyl ligand as an efficient catalyst for this reaction operating under highly acidic conditions. Valuable N-alkoxy amines can be accessed at room temperature with nondetected overredn. of the N-O bond [e.g., (E)-I → (S)-II (97%, 97.5:2.5 er)]. Catalyst turnover numbers up to 4000 and enantiomeric ratios up to 98:2 are observed The findings serve as a blueprint for the development of metal-catalyzed enantioselective hydrogenations of challenging substrates.

Category: dioxole. 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-Bromomethyl-1,3-dioxolane, is researched, Molecular C4H7BrO2, CAS is 4360-63-8, about Transition-Metal-Free Deconstructive Lactamization of Piperidines. Author is Romero-Ibanez, Julio; Cruz-Gregorio, Silvano; Sandoval-Lira, Jacinto; Hernandez-Perez, Julio M.; Quintero, Leticia; Sartillo-Piscil, Fernando.

One of the major challenges in organic synthesis is the activation or deconstructive functionalization of unreactive C(sp3)-C(sp3) bonds, which requires using transition or precious metal catalysts. We present here an alternative: the deconstructive lactamization of piperidines without using transition metal catalysts. To this end, we use 3-alkoxyamino-2-piperidones, which were prepared from piperidines through a dual C(sp3)-H oxidation, as transitory intermediates. Exptl. and theor. studies confirm that this unprecedented lactamization occurs in a tandem manner involving an oxidative deamination of 3-alkoxyamino-2-piperidones to 3-keto-2-piperidones, followed by a regioselective Baeyer-Villiger oxidation to give N-carboxyanhydride intermediates, which finally undergo a spontaneous and concerted decarboxylative intramol. translactamization.

Author is Tarasova, O. A.; Nedolya, N. A.; Albanov, A. I.; Trofimov, B. A..

The sequential reaction of lithiated methoxyallene, Me isothiocyanate, and 2-(bromomethyl)-1,3-dioxolane in the presence of CuBr yields a 2,3-disubstituted thiophene instead of the expected pyrrole. The process was accomplished in one preparative stage and involved intramol. cyclization of the in situ-generated lithium allenylimidothioate and N-alkylation of the resulting lithium thienylamide. Varying the reaction conditions did not affect its route: in all cases, the only product was N-(1,3-dioxolan-2-ylmethyl)-3-methoxy-N-methylthiophen-2-amine.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Molecules called Efficient synthesis of α-branched purine-based acyclic nucleosides: scopes and limitations of the method, Author is Frydrych, Jan; Slaveetinska, Lenka Postova; Draccinsky, Martin; Janeba, Zlatko, which mentions a compound: 4360-63-8, SMILESS is BrCC1OCCO1, Molecular C4H7BrO2, Related Products of 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.
