A convenient method of synthesizing 2-amino-1,2-dihydroisoquinoline-3(4H)-one and its amide derivatives (4 or 5) is described through sydnone intermediate (3) derived from TIC (1) (tetrahydroisoquinoline-3-carboxylic acid) under acidic conditions in good yield.
通过TIC(1)的sydnone中间体(3)(四氢异喹啉3- )描述了一种方便的合成2-amino-1,2-dihydroisoquinoline-3(4 H)-及其酰胺衍生物(4或5)的方法羧酸)在酸性条件下的收率很好。
