A chemoenzymatic straightforward synthesis of (R)-(+)-α-(4-fluorophenyl)-4-methyl-1-piperidinebutanol (2) and (R)-(+)-α-(4-fluorophenyl)-4-(2-pyrimidinyl)-1-piperazinebutanol (3), two potential antipsychotic agents, has been developed by two different approaches involving lipasemediated resolution of the racemic compounds or through asymmetrization of the precursor alcohol 4. A second enzymatic resolution
化学酶法直接合成(R) -(+)-α-(4-氟苯基)-4-甲基-1-哌啶丁醇(2)和(R)-(+)- α-(4-氟苯基)-4- (2-嘧啶基)-1-哌嗪丁醇(3),两种潜在的抗精神病药,已通过两种不同的方法开发,涉及脂肪酶介导的外消旋化合物的拆分或通过前体醇4的不对称化。第二次酶解,然后将(R)-4与4-甲基哌啶(6)或1-(2-嘧啶基)哌嗪(7)缩合,得到的(R)-2和(R)-3具有良好的化学性质和优异的光学收率(> 99%ee)。
