During the stereospecific synthesis of diastereoisomeric (+)-1-phenyl-1,2-dimethyl-3-dimethyl-amino-propan-1-ols (III and IV), obtained by reaction of suitable Grignard reagents on α-methyl-β-dimethylamino-propiophenone (I) or on 3-methyl-4-dimethylamino-butan-2-one (II) respectively, the absolute configuration of (−)-amino-alcohol (III) was shown to be 1R, 2S. It was also established that (−)-amino-alcohol
在非对映异构体(+)-1-苯基-1,2-二甲基-3-二甲基-氨基丙烷-1-醇(III和IV)的立体定向合成过程中,通过合适的格氏试剂在α-甲基-β上反应获得分别在-二甲基氨基-苯乙酮(I)或3-甲基-4-二甲基氨基-丁-2-酮(II)上,(-)-氨基醇(III)的绝对构型显示为1 R,2 S。还确定了(-)-氨基醇(IV)具有1 S,2 S构型。
