Synthesis of 1‐Pyrroline by Denitrogenative Ring Expansion of Cyclobutyl Azides under Thermal Conditions
We herein report an efficient and systematic synthesis of 1-pyrrolines from cyclobutyl azides under thermal and neutral conditions. The reaction proceeded without any additional reagents, and nitrogen was generated as the sole by-product. Furthermore, the generated 1-pyrrolines could be continuously transformed into pyrroles, N-Boc-amines, and oxaziridines in an one-pot manner.

A rhodium-catalyzed enantioselective click cycloaddition of azides and alkynes for rapid and modular access to atropisomeric triazoles is reported. This click process features very mild reaction conditions, superior efficiency and enantioselectivity, broad substrate scope and facile scalability. The racemization study and further derivatizations demonstrate the good configurational stability of the
