(+)-N,N'-diphenyl tartaric acid diamide 2, (+)-N,N'-dibenzyl tartaric acid diamide 3, (+)-dicyclohexyl tartaric acid diamide 4, and (+)-N,N'-di-n-octyl tartaric acid diamide 5 are synthesized via the amidate of diethyl tartarate and corresponding amine, respectively. Chiral tin complexes 6 are also prepared by treatment of tin dichloride with 2 equiv. of doubly deprotonated tartaric acid diamide followed by addition of an allylic bromide. The reaction of 6 with benzaldehyde affords optically active homoallyic alcohols in 42~64% yield and in 24~62% e.e..
