Abstract
AbstractAn annulation strategy based on ketene dithioacetals is described. Under very mild conditions, a number of pyrrolidinetriones 2 and piperidinetriones 3 have been synthesized by the cycloaddition reaction of α‐carbamoyl ketene dithioacetals 1 with di‐carboxylic acid dichlorides in good to excellent yields. Further application of this protocol is highlighted by the synthesis of a set of fused pyrimidine derivatives 4/5 from 2/3 and amidines.
