摘要 由天然樟脑合成了两个新的手性氨基醇,并对其在二乙基锌对芳香醛的对映选择性加成中的催化性能进行了研究,其中一个化合物4b催化苯甲醛和二乙基锌的加成反应获得了85%化学产率和73%e.e.。 Two new chiral amino alcohols were synthesized from (+)-camphor, and their application to the enantioselective addition of diethylzinc to aldehydes was described. One of the ligands showed a good asymmetric induction in the catalysis of the reaction of benzaldehyde, and provides a yield of 85 % and 73 % e.e.
