A novel procedure for the synthesis of N-unsubstituted β-enamino thioesters, (Z)-S-phenyl 3-amino-3-arylprop-2-enethioates, from 3-arylisoxazoles or 3-aryl-5-phenylthio-2-isoxazolines is described and a plausible mechanism for the reaction is proposed. Some examples of conversion of one β-enamino thioester [(Z)-S-phenyl 3-amino-3-phenylprop-2-enethioate] into N-unsubstituted β-enaminoacyl derivatives (β-enamino esters, β-enamino amides, and β-keto amides) are also reported.
