Three Component Reaction

This work describes the synthesis of compounds containing thiazolidine and propargylamidic motifs. Their preparation follows a synthetic route containing two multicomponent reactions. First, the Asinger four-component reaction is used to prepare 3-thiazolines and 3-oxazolines. Secondly, these heterocyclic imines are converted into propargylamides by a copper-catalyzed three-component reaction using acyl chlorides and terminal alkynes. The synthetic route is characterized by mild conditions and many functional groups are tolerated. The formation of an unexpected α-alkynoxyamide is also presented.

Multicomponent reactions (MCRs) play an important role to create the molecular complexity in a one-step process. Based on the mechanism and process of Mannich-type reactions in the synthesis of Grammin, arylthiomethylation reactions of indole were performed by using three components: indole, p-thiocresol and a solution of formaldehyde (36%) under two activation conditions, e.g. magnetic stirring and ultrasonic irradiation. The main product, 3-(p-tolylthiomethyl)-1H-indole, was obtained in a moderate yield (54%) under short irradiation (40 minutes) by probe sonicator.
