A diastereoselective carbocyclisation of allene-hydrazones through the intramolecular allylic transfer reaction.
A diastereoselective synthesis of cyclic hydrazines was achieved from a carbocyclisation of allene-hydrazones by the Pd-catalyzed distannylation of an allene moiety, followed by the transmetallation of allylic stannane intermediates with TiCl4.
