The reaction of chiral aluminium alkoxides (2)[(–)-menthyloxide (2a); (–)-2-methylbutoxide (2b); (–)-2-butoxide (2c); and (–)-2-bornanyl oxide (2d)] with (RS)-2-phenylpropanal (1) gives the optically active (S)-(–)-2-phenylpropyl (R)-(–)2-phenylpropanoate (3), and the mixed esters (–)-menthyl 2-phenylpropanoate (5a),(+)-2-phenylpropyl 2-methylbutanoate (4b), and (+)-2-methylbutyl 2-phenylpropanoate
手性铝醇盐(2)[(-)-薄荷醇(2a); (–)-2-甲基丁氧基(2b);(–)-2-丁氧基(2c);和(–)-2-降冰片烯氧化物(2d)]与(RS)-2-苯基丙醛(1)一起生成旋光性(S)-(–)-2-苯基丙基(R)-(–)2-苯基丙酸酯( 3),以及分别的混合酯(-)-2-苯基丙酸薄荷酯(5a),(+)-2-苯基丙基2-甲基丁酸(4b)和(+)-2-甲基丁基2-苯基丙酸酯(5b)。对于化合物(1),提出了不对称歧化反应机理。
