UNUSUAL COURSE OF THE REACTION OF N-(TOSYLMETHYL)THIOUREA AND N-(AZIDOMETHYL)THIOUREA WITH SODIUM ENOLATE OF DIMEDONE

Abstract

The end product of the reaction of N-(tosylmethyl)thiourea or N-(azidomethyl)thiourea with sodium enolate of dimedone is bis(2-hydroxy-4,4-dimethyl-6-oxocyclohex-1-enyl)methane (methylenebis-dimedone) instead of the expected 8a-hydroxy-7,7-dimethyl-2-thioxoperhydroquinazolin-5-one.
