(S)-1-Phenyl-3-buten-1-ol (1), prepared in high optical purity by enzymatic resolution of the racemate, is a convenient building block for the synthesis of (R)-fluoxetine (7a) and (R)-tomoxetine (7b). Compound 1 was converted to the title drugs by etherification with appropriate phenols under Mitsunobu conditions, ozonolysis of the terminal double bond, mesylation of the resulting alcohol and substitution
(S)-1-苯基-3-丁烯-1-醇(1)是通过消旋体的酶促拆分以高光学纯度制得的,是合成(R)-氟西汀(7a)和( R)-托莫西汀(7b)。通过在Mitsunobu条件下用适当的酚醚化,末端双键的臭氧分解,所得醇的甲磺酸化和用甲胺取代,将化合物1转化为标题药物。
