A new method for the synthesis of α-amino phenylpropanoids under blue light-emitting diode irradiation has been developed through α-C-H benzylation of readily available N-phenyl glycine ester with benzyl oxalates as a coupling partner under mild conditions. A range of N-phenyl glycine esters were successfully converted to α-amino phenylpropanoid products in moderate to good yields. The utility of this
通过在温和条件下将容易获得的N-苯基甘氨酸酯与草酸苄酯作为偶联伙伴进行α-CH苄基化,开发了一种在蓝色发光二极管照射下合成α-氨基苯丙素的新方法。一系列N-苯基甘氨酸酯已成功转化为 α-氨基苯丙素产品,收率中等至良好。该方法的实用性通过其在天然产物后期修饰中的应用而得到强调。
