The absolute configuration of (+)-α-methyl-β-dimethylaminopropiophenone (Ia) was found to be S by chemical correlation with R(−)-α-methyl-β-alanine. The absolute configuration of (+)-α-methyl-β-piperidino- and of (−)-α-methyl-β-morpholinopropiophenone (Ib and Ic) was found to be S and R, respectively, by comparison of their ORD spectra with that of the keto-base (Ia).
通过与R(-)-α-甲基-β-丙氨酸的化学相关性,发现(+)-α-甲基-β-二甲基氨基苯乙酮(Ia)的绝对构型为S。通过比较它们的ORD光谱,发现(+)-α-甲基-β-哌啶子基和(-)-α-甲基-β-吗啉代苯乙酮(Ib和Ic)的绝对构型分别为S和R.与酮基(Ia)相同。
