Ternary Condensation of Biginelli Thiones, Chloroacetic Acid, and Aldehydes as an Effective Approach Towards Thiazolo[3,2-a]pyrimidines and 5-Arylidenethiazolidine-2,4-diones. -The three-component reaction of thiones (I) with aldehydes (II) and chloroacetic acid readily affords thiazolo[3,2-a]pyrimidines (IV), whilst prolonged reaction times leads to the formation of hydrolysis products (V). -(LEBEDYEVA*, I.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
