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.

Compound: 2-Bromomethyl-1,3-dioxolane, is researched, Molecular C4H7BrO2, CAS is 4360-63-8, about Transition-Metal-Free Deconstructive Lactamization of Piperidines.Recommanded Product: 4360-63-8.

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.

Ruthenium(II) biscarboxylate catalysis enabled efficient hydrogen isotope exchange of acrylic C-H bonds with user-friendly D2O. The C-H labeling was characterized by excellent positional selectivity and a broad functional group tolerance. The deuteration was successfully conducted on 55 mmol scale with TONs of >1000, while mechanistic studies provided insights into ruthenium(II) oxidase catalysis. The obtained deuterated alkenes enabled the synthesis of labeled standards for mass spectrometry of irradiated foodstuffs.
