Copper-catalyzed synthesis of thiazolidine derivatives via multicomponent reaction of terminal alkynes, elemental sulfur, and aziridines

Abstract

An atom-economic catalytic multicomponent reaction between terminal alkynes, elemental sulfur, and aziridines has been reported. In this transformation, alkyne thiolate derived from the reaction of terminal alkynes and elemental sulfur in the presence of CuOTf/DBU reacted with aziridines to afford thiazolidine derivatives.
