Condensation de mercaptoacétates et de mercaptopropionates d'alkyle sur les 2-dialkylaminométhylpropènenitriles
Written by sctunisie no comments2-dialkylaminomethylpropenenitriles 1 react with alkyl mercaptoacetates and mercaptopropionates to give respectively dihydrothiophenes 3 and thiopyranones 5. From a mechanistic view point, the reaction leads to thiopyranones 5, proceeds by the intermediary β-mercaptoester 4 which was isolated.
