Abstract

A series of strained bi- and tricyclic amides has been shown to be unusually sensitive to cleavage of the C-N bond adjacent to the amide moiety. This bond undergoes facile breaking when subjected to treatment with H2/Pd(OH)2, MeI, and DDQ. In each case, the reaction is highly regioselective and mainly results in breaking the C-N bond that deviates the farthest from its natural planar state. Preliminary experiments that bear on the mechanisms of these reactions are described.

摘要

一系列的张力双环和三环酰胺已被证明对酰胺部分相邻的C-N键的断裂异常敏感。当用H2/Pd(OH)2、MeI和DDQ处理时,该键容易断裂。在每种情况下,反应都具有高度的区域选择性,主要导致偏离其天然平面状态最远的C-N键断裂。描述了与这些反应机制相关的初步实验。
