Abstract

A simple synthetic protocol was developed for the efficient synthesis of functionalized (1-benzo[d]thiazol-2-ylimidazolidin-4-ylidene)acetates via a three-component reaction among 2-aminobenzothiazole, α,β-unsaturated N-arylaldimines, and dialkyl acetylenedicarboxylates in anhydrous dichloromethane at room temperature. Additionally, the three-component reaction with 2-aminothiazole afforded the corresponding (1-thiazol-2-ylimidazolidin-4-ylidene)acetates.
