The azetidine group is frequently encountered within contemporary medicinal chemistry. However, the introduction of an azetidine can be synthetically challenging. Herein, a straightforward synthesis of azetidine-3-amines, starting from a bench stable, commercial material is presented. The reaction tolerates common functionality and proceeds in moderate-to-high yield with secondary amines, and moderate-to-low yield with primary amines. The methodology compares favorably to alternative procedures and can be utilized in "any-stage"functionalization, including late-stage azetidinylation of approved drugs and other compounds with pharmacological activity.
