We have achieved a simple and convenient synthesis of several C(4) substituted 5-ylidenepyrrol-(5H)-ones from 3-aryl/heteroaryl/alkyl 3-cyanopropionates and ethyl/methyl bromoacetates via a useful variation of the classical Blaise reaction. The produ

A conceptually new synthesis of pyridine rings by a [C4 + CN] assembly has been developed by applying a vinylogous version of the classic Blaise reaction. The zinc-mediated reaction of (het)aryl or alkyl nitriles with ethyl-4-bromocrotonate provided
