Variation of R 2 was also studied, and aromatic groups with electron-donating groups in the para position gave good yields and good levels of chirality transfer, with moderate diastereoselectivities (6l-6m). Para-trifluoromethyl-substituted allylic amine 4n gave aliphatic amine 6n with a decreased efficiency in terms of yield and chirality transfer, but the diastereoselectivity was enhanced. Meta-methyl-substituted 6o was also obtained in high yield with excellent levels of chirality transfer. Heteroaryl derivative 6p was obtained in excellent yield with high levels of chirality transfer. Replacing the aryl substituent by H had a significant effect on the yield of the reaction, and 6q was obtained in 65% yield. A gram-scale experiment was carried out on amine 4d (Scheme 3). Aliphatic amine 6d was obtained in 73% yield, with excellent levels of chirality transfer (91%) and good levels of diastereoselectivity (72:28). In addition, the absolute configurations of both allylic amine 4d and major diastereomer 6d were determined by X-ray single crystal diffraction analysis (Scheme 3 and Figures ), and the absolute configuration of the other chiral amines (6a-6r) was assigned by analogy.
