摘  要:以自制的(R,R)-Salen-Co(Ⅲ)·BF3(4)催化外消旋?-萘基缩水甘油醚(2)的水解动力学拆分,获得高光学纯度的(S)-?-萘基缩水甘油醚[(S)-2]和(R)-3-(?-萘氧基)-1,2-丙二醇(5),并采用Sharpless的"一锅法"将5转化为(R)-2。(R)-2和(S)-2分别与1-(2-甲氧基苯基)哌嗪(3)反应得到(R)-和(S)-萘哌地尔,ee值98%。(S) -Naphthylglycidic ether [ (S) -21 and (R) -3- (ct-naphthoxy) -1,2-propanediol (5), the key chiral building block, were obtained with high enantiomeric excess by means of hydrolytic kinetic resolution (HKR) of naphthylglycidic ether (2) with (R,R) -Salen Co (III) "BF3 complex (4), and then 5 was converted into (R) -2 by "one-pot" procedure which was developed with Sharpless. Optical pure compounds 2 were further transformed into corresponding (R) - and (S) -naftopidil by treatment with 1- (2-methoxyphenyl) piperizine (3), respectively. The enantiomeric excess of (R) - and (S) -naftopidil were both 98 %.
