Heterocyclic system containing bridgehead nitrogen atom: Facile one-pot synthesis of imidazo[2,1-b] thiazoles and thiazolo[3,2-a]pyrimidines using [hydroxy(p-tosyloxy)iodo]benzene

Mohan,Verma,Singh

, p. 1293 - 1298 (1992)

A one-pot synthesis of 4,5,6,7-tetrahydrothiazolo[3,2-a]pyrimidines (IIb) and 5,6-dihydro-4H-imidazo[2,1-b]thiazoles (IIa) have been achieved by the reaction of ketones in the presence of [hydroxy(p-toxyloxy)iodo]benzene with 2-mercapto-3,4,5,6-tetrahydro
