The oxidative functionalization of olefins is a common method for the formation of vicinal carbon-heteroatom bonds. However, oxidative methods to transform allenes into synthetic motifs containing three contiguous carbon-heteroatom bonds are much less developed. The use of bicyclic methylene aziridines (MAs), prepared via intramolecular allene aziridination, as scaffolds for functionalization of all three allene carbons, among other reactions, is described herein.

Propargylic amines are important intermediates for the synthesis of nitrogen-containing heterocycles. The insertion of a nitrene into a propargylic C–H bond has not been explored, despite the attention directed toward the Rh-catalyzed amination of other types of C–H bonds. In this communication, the conversion of a series of homopropargylic carbamates to propargylic carbamates and aminated allenes
