Three-component reactions of aldehydes, ammonia, and allylboronates were found to provide homoallylic primary amines in high yields with high chemo- and stereoselectivities. A two-step, one-pot, stereoselectivesynthesis of an uncommon alpha-amino acid, alloisoleucine, was achieved utilizing this reaction.
