Cyclic amines such as pyrrolidine and 1,2,3,4-tetrahydroisoquinoline undergo redox-annulations with alpha,beta-unsaturated aldehydes and ketones. Carboxylic acid promoted generation of a conjugated azomethine ylide is followed by 6pi-electrocylization, and, in some cases, tautomerization. The resulting ring-fused pyrrolines are readily oxidized to the corresponding pyrroles or reduced to pyrrolidines. This journal is

By employing a MOF-templated method, we have developed a highly dipersed and ultralow loading cobalt nanocatalyst, which has been applied in the oxidative functionalization of easily available cyclic amines with 2-aminoarylmethanols to ring-fused quinazolinones, the core structures of numerous valuable products. The developed catalytic transformation proceeds with the merits of broad substrate scope, good functional group tolerance and chemoselectivity, high step- and atom-efficiency, and use of the naturally abundant Co/O2 system, which offers a practical way for the preparation of quinazolinones with structural diversity. The work presented has built an important basis for direct conversion of cyclic amine motifs into functional frameworks.

An efficient Lewis acid-catalyzed C(sp3)?C(sp3) bond forming annulation reaction has been developed. This strategy serves as a new method for the facile synthesis of tetrahydro-5H-isoquinolino[2,1-g][1,6]naphthyridine derivatives.

A practical protocol has been developed here for the Mn(II)-catalyzed N -acylation of amines with high yields using N, N -dimethylformamide and other amides as the carbonyl source. The protocol is simple, does not require any acid, base, ligand, or other additives, and encompasses a broad substrate scope for primary, secondary, and heterocyclic amines.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C9H10BrN, you can also check out more blogs about17680-55-6

Secondary amines react with thiosalicylaldehydes in the presence of catalytic amounts of acetic acid to generate ring-fused N,S-acetals in redox-neutral fashion. A broad range of amines undergo alpha-sulfenylation, including challenging substrates such morpholine, thiomorpholine, and piperazines. Computational studies employing density functional theory indicate that acetic acid reduces the energy barriers of two separate steps, both of which involve proton transfer.

The oxidation of N-phenyltetrahydroisoquinolines occurs rapidly with DDQ. Under ambient conditions and in the presence of nitromethane, the corresponding beta-nitroamine derivatives are isolated in good to excellent yields. Variation in the electronic nature of the isoquinoline and the N-phenyl substituent showed that a broad range of substituents are tolerated, with electronic communication between the isoquinoline aromatic ring and the C1 carbon being stronger than with the N-aryl ring. Reduction of the beta-nitroamines to the corresponding novel chiral vicinal diamines are straightforward. Examination of the reaction by 1H NMR spectroscopy suggested that the reaction proceeds via an iminium ion, which then reacts with nitromethane upon work-up. This information was used to shorten the required reaction time.
