Abstract

Heterocyclic Synthesis, Pyrrolones The behaviour of 4-benzylidene-2-oxazolin-5-one (2) and of 4-phenylazo-2-oxazolin-5-one (3) toward a variety of active methylene reagents is reported. Cleavage of the oxazolin-5-one ring was observed in most cases. A variety of new, otherwise, difficult accessible, azolyl derivatives could be prepared.
