“…In this case, the cyclization took place only to the nitrogen at position 3 in the pyrimidine system. Similarly, ethyl 5-oxo-2,3,6,9-tetrahydro-5H-pyrido [4 ,3 :4,5]thieno [2,3-d] [1,3]thiazolo[3,2-a]pyrimidine-8(7H)-carboxylate 10 was obtained from the reaction of 2 with aminoethanethiol hydrochloride in pyridine (Scheme 1).…”

“…The antiparasitic properties exhibited by a variety of isothiocyanates have been very well documented [1]. Furthermore, various substituted thioureas also have been reported to possess broad-spectrum anthelmintic activity [2].…”

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.
