A new reaction model, tandem Michael addition/formal isocyanide insertion into the acyl C–C bond, has been developed. Thus, a series of 2-acylpyrroles and seven-/eight-membered ring fused pyrroles were synthesized from the reaction of methyl isocyanides with enones in a single operation.
已经开发了一种新的反应模型,即串联式迈克尔加成反应/形式的异氰酸酯插入酰基C-C键。因此,在一次操作中,由甲基异氰化物与烯酮的反应合成了一系列的2-酰基吡咯和七元/八元环稠合的吡咯。
