Abstract

N-Acyl-N,O-acetals are key components in a variety of bioactive natural products. Furthermore, they are synthetic equivalents of unstable N-acylimines and building blocks in organic synthesis. Tremendous efforts have been made in the synthesis of such acetals, these methods can be broadly classified into two categories: electrochemical oxidation and chemical methods. Herein, we will summarize progress in the preparation of these subunits, which may aid the development of new synthetic methods for N-acyl-N,O-acetals.
