This paper describes the synthesis and use of beta-hydroxylamino imides derived from D-glyceraldehyde possessing a number of reactive sites that operate synergistically or alternatively to bring about highly regio- and diastereoselective transformations to give an optically pure aziridine-2-imide, a dihydro pyrimidine-2,4-dione, or a lactone. Both the syntheses, via the diastereoselective 1,4-conjugate
本文描述了衍生自D-甘油醛的β-羟氨基酰亚胺的合成和用途,该衍生物具有许多协同作用的反应位点,或者可进行高区域和非对映选择性转化,从而生成光学纯的氮丙啶2-酰亚胺(二氢)嘧啶-2,4-二酮或内酯。通过将O-苄基羟胺非对映选择性的1,4-共轭加成到α,β-不饱和酰亚胺上,两种合成都可以通过在不同的路易斯酸之间进行选择来简单地调节。
