Intramolecular Cycloaddition of Imines of Cysteine Derivatives*
نویسنده
چکیده
Azomethine ylides were generated from Schiffs bases of S-allylcysteine methyl ester and their intramolecular 1,3-dipolar cycloadditions were studied. These reactions led to the synthesis of thieno[3,4b]pyrrole derivatives in good yield.
