Regioselective Synthesis of 2-Functionalized Thiophenes by Condensation of α-Mercapto Compounds with β-Aminoenone Derivatives

2-Acylthiophenes and ethyl 2-thiophenecarboxylates are prepared regioselectively by reaction of 3-chloroenones and 2-acylenammonium chlorides with α-mercapto derivatives in good to moderate yields.
