The coupling reaction allows simple structural fragments to be constructed and sequentially assembled by C-X bond synthesize a variety of active molecular frameworks. Different from the traditional single-metal catalyst, synergistic effect bimetal provides special catalytic activity that cannot obtained thus emerging as an efficient alternative mode. In this paper, we used Cu-Al bimetallic heterogeneous mesoporous materials participate in sequential assembly C-S C-N bonds, which effectively catalyzed synthesis 2-substituted benzothiazole heterocyclic systems. addition, GW610 with antitumor was synthesized easily efficiently strategy.

Herein a novel and concise approach to pyrrole skeletons via Pd-catalyzed tandem cyclization reactions is investigated. The substrates for the transformation could be readily prepared by phosphoric acid-catalyzed Ugi with available starting materials. In this strategy, two isocyanides participate in sequential isocyanide insertion reactions, chemoselectivity of products regulated steric hindrance isocyanide. A plausible mechanism formation corresponding adducts proposed.

Abstract Regioselective coupling reaction of N-substituted imidazoles with isocyanates in the presence a stoichiometric amount hydrosilanes catalyzed by Ir4(CO)12 to give imidazole-2-carboxamides is reported. Imidazoles bearing an (O-silyl)carboximidate group at 2-position appear be initially formed reaction; these are then hydrolyzed final products situ. The addition hydrosilane was essential for catalytic proceed. Substituents on imidazole ring had no effect reaction, except certain bulky substituents such as t Bu and Ph groups 4-position. Triazoles 4-methyl-4H-1,2,4-triazole 1-methyl-1H-1,2,4-triazole were also applicable this C–H amidation, latter proceeded regioselectively carbon atom between sp3 sp2 nitrogen atoms ring, not two atoms.
