A new series of chiral β-amino alcohols derived from (S)-leucine has been synthesized. The amino alcohol possessing a piperidine ring and a phenethyl group on the carbinol carbon atom was found to be an efficient ligand to catalyze the enantioselective addition of diethylzinc to aromatic (up to 97% ee) and aliphatic (up to 95% ee) aldehydes.
合成了一系列新的衍生自(S)-亮氨酸的手性β-氨基醇。发现在甲醇碳原子上具有哌啶环和苯乙基的氨基醇是催化二乙基锌与芳族(至多97%ee)和脂肪族(至多95%ee)醛的对映选择性加成的有效配体。
