Abstract

An efficient two-step Ugi/cyclization reaction sequence provides hydantoins. This microwave-assisted one-pot cyclization strategy, in which an alkyne group acts as a leaving group under basic conditions, could be applicable to other multicomponent reactions (MCRs) for synthesizing bioactive and drug-like hydantoins.
