KOH‐Oriented Ring Openings of N‐Tosylaziridines with Carboxylic Acids in DMSO

A facile and efficient KOH‐oriented regioselective ring‐opening reaction for the acetolysis of N ‐tosylaziridines in DMSO was developed under mild conditions. This operationally simple protocol could tolerate a variety of functionalized carboxylic acids as well as several N ‐tosylaziridines. Moreover, this strategy provided the corresponding ring‐opening products with good results.
