activation within the last decade. However, cleavage of its robust amide bond has shown to be challenging in several cases, thus jeopardizing the general synthetic utility of the method. To overcome this limitation, we herein report a simple oxidative deprotection protocol. This transformation rapidly converts the robust amide to a labile imide, allowing subsequent cleavage in a simple one‐pot fashion to rapidly
在过去十年中,8-氨基喹啉已成为 C-H 活化历史上最强大的二齿指导基团之一。然而,在几种情况下,其坚固的酰胺键的裂解已被证明具有挑战性,从而危及该方法的一般合成效用。为了克服这一限制,我们在此报告了一种简单的氧化脱保护方案。这种转化迅速将坚固的酰胺转化为不稳定的酰亚胺,从而允许以简单的单锅方式进行后续裂解,从而快速获得羧酸或酰胺作为最终产品。
