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.
一种合成N-未取代的β-烯胺硫酯,即(Z)-S-苯基3-氨基-3-芳基丙-2-烯硫酯的新方法,通过3-芳基异噁唑或3-芳基-5-苯硫基-2-异噁唑啉来实现,并且提出了该反应的可能机理。此外,还报道了一些将一种β-烯胺硫酯[(Z)-S-苯基3-氨基-3-苯基丙-2-烯硫酯]转化为N-未取代的β-烯胺酰基衍生物(β-烯胺酯、β-烯胺酰胺和β-酮酰胺)的实例。
