With Tf2O as the activation reagent, a mild and general method has been developed for the bisphosphonylation of both secondary and tertiary amides. The protocol is highly efficient and chemoselective, and it tolerates a number of sensitive functional groups such as cyano, ester, and aldehyde groups.
用Tf 2 O作为活化剂,已经开发了一种温和而通用的方法用于仲酰胺和叔酰胺的双膦酰化。该协议高效且具有化学选择性,并且可以耐受许多敏感的官能团,例如氰基,酯和醛基。
