A novel approach, involving X-ray analysis of a specifically designed racemate, in combination with correlations by circular dichroism, allows the absolute configuration of the spiro lactam 4 to be determined. The outcome is that the enantiomer of this lactam which strongly inhibits uroporphyrinogen III synthase (cosynthetase) has the R-configuration and the implications of this finding are briefly
一种新颖的方法,包括对专门设计的外消旋物的X射线分析,以及通过圆二色性的相关性,可以确定螺内酰胺4的绝对构型。结果是,这种内酰胺的对映异构体强烈抑制尿卟啉原III合酶(辅酶),具有R-构型,并简要讨论了这一发现的含义。
