Real-time monitoring of a cobalt-mediated one-pot transition metal-catalyzed multicomponent reaction
A series of nine novel 3-tetrazolylmethyl-azepino[4,5-b]indol-4-ones were prepared in moderate to good overall yields in only two reaction steps. The first step consisted of a one-pot sequential process of an Ugi-azide multicomponent reaction, N-acylation and SN2 to give the xanthates. The second step was an intramolecular cyclization under free radical conditions. Also, their binding modes hav...
An efficient and one-pot procedure for the synthesis of arylated and stereodefined allylic alcohols has been achieved through zirconium-mediated multicomponent coupling reactions of alkynes, aldehydes (or ketones), and aryl iodides. The subsequent intramolecular Friedel-Crafts reactions of these allylic alcohols catalyzed by Brønsted or Lewis acids afford highly substituted indenes and spiroind...
