Branched allylic amines were prepared by Ir-catalyzed enantioselective allylic aminations with the bulky N-nucleophiles HN(Boc)2 and HNBn2. The products were transformed into N-protected amino aldehydes, which were either reduced or coupled diastereoselectively with organometallic compounds to give vicinal amino alcohols. A formal synthesis of the neurokinin receptor antagonist (+)-L-733060 was carried out as an application. Ir-catalyzed enantioselective allylic aminations with bulky N-nucleophiles HN(Boc)2 and HNBn2 gave N-protected allylic amines, which were transformed into N-protected chiral amino aldehydes. These are useful chiral building blocks as previously demonstrated by Reetz et al. A formal synthesis of the neurokinin receptor antagonist (+)-L-733060 was carried out as an application.
