We studied methods of stereospecific synthesis that enabled us to obtain variously substituted morpholinic compounds and to determine their absolute configuration. From a study of the chiroptical properties of synthetic N-[2-pyridyl-N-oxide] derivatives of optically active morpholines, it was possible to correlate the sign of the Cotton effect with the absolute configuration. This correlation agrees
我们研究了立体有择合成方法,使我们能够获得各种取代的吗啉代化合物并确定其绝对构型。通过对光学活性吗啉的合成N- [2-吡啶基-N-氧化物]衍生物的手性性质的研究,可以将Cotton效应的征兆与绝对构型相关联。这种相关性与先前针对哌啶类型的衍生物建立的相关性一致。通过评估位置2和3上取代基对棉花效应的各种贡献,我们建立了在上述两个位置上缩合的双环化合物的绝对构型。
