以1,3-二溴丙酮和(2′S)-(二苯基羟甲基)-四氢吡咯为原料,合成了两种新型手性氨基醇1,3-双[(2′S)-(二苯基羟甲基)-1-四氢吡咯基]丙酮(3)和1,3-双[(2′S)-(二苯基羟甲基)-1-四氢吡咯基]-2-丙醇(4),总产率分别为39%和35%.手性双氨基醇3-/4-Et2Zn可催化未修饰醛、酮的不对称直接羟醛缩合反应,对映体过量最高9%.

Two novel chrial bisaminoalcohols,1,3-bis-[(2′S)-(diphenylhydroxymethyl)pyrrolidin-1-yl]-2-pro~pa~none (3) and 1,3-bis-[(2′S)-(diphenylhydroxymethyl)pyrrolidin-1-yl]-2-propanol (4), were prepared using the 1,3-dibromo-2-propanone and (2′S)-(diphenylhydroxymethyl)pyrrolidine as the starting materials. The yields were 39% and 35%, respectively. The asymmetricdirect aldol reactions of unmodified ketones and aldehydes were achieved with the ee up to 9% by using the bisaminoalcohol-diethylzinc as the catalyst.

Key words: chiral β-aminoalcohol, direct aldol reaction, catalyst
