Abstract

The CrabbØ homologation allows the synthesis of allenes from in situ generated propargylamines through a 1, 5-hydride shift/1, 2-elimination sequence(Equation (1), Scheme 1).[1] Initially developed for the synthesis of monosubstituted allenes, reaction conditions have now been established allowing access to di-and trisubstituted allenes.[2–3] A recent important discovery came from the research group of Nakamura who reported the ...
