O-Acyl ketoximes has been proven to be versatile building blocks for practical construction of N-heterocycles. In the last few years, diverse catalytic systems have been discovered to enable efficient transformations of O-acyl ketoximes to a range of nitrogen-heterocycles. Herein, we summarized our recent examples of novel nitrogen-heterocycle formation with new function findings of O-acyl ketoximes through facile aerobic copper catalysis, metal-free NO bond activation, multi-component assembly, and bis-annulations. From the green chemistry perspective, these works represent efficient methods with high atom economy, high selectivity, and minimized chemical waste. These findings also complement well to the previous mainly copper-based catalytic systems and more importantly enrich the oxime chemistry in organic synthesis.
