phenyl-phosphonic dichloride. Crystal structure of (I) and (III) exhibit monoclinic symmetries as (II) exhibits orthorhombic symmetry. Their packings are ensured by a combination of different types of weak non-covalent and competitives effects, in particular, π/π stacking against CH/π hydrogen bonds. The significance of this study lies in the comparison drawn between these crystal structures and those
摘要 通过 X 射线衍射确定了三种 3-benzyl-2-phenyl-1,3,2-oxazaphospholidin-2-one 衍生物的晶体结构。化合物 (I)、(2S) 和 (2R)-3-benzyl-2-phenyl-1,3,2-oxazaphospholidin-2-one 的外消旋混合物、化合物 (II)、(2S,4S)-的合成3-benzyl-2-phenyl-4-(propan-2-yl)-1,3,2-oxazaphospholidin-2-one和化合物(III),(2S,4S)和(2R,4S)的混合物- 3,4-二苄基-2-苯基-1,3,2-oxazaphospholidin-2-one 很容易从相应的 N-保护氨基醇和苯基膦酰二氯开始进行。(I) 和 (III) 的晶体结构表现出单斜对称性,因为 (II) 表现出正交对称性。它们的堆积是通过不同类型的弱非共价和竞争效应的组合来确保的,特别是针对
