We describe a novel asymmetric approach using Staudinger chemistry to proline-derived spiro-β-lactams. A chiral group at C-4 of the acid chloride of proline directs the stereoselectivity of Staudinger chemistry and later is sacrificed to obtain optically active 5.4-spiro-β-lactams. The scope, limitations, and mechanistic rationale for the observed results of Staudinger Chemistry of the acid chloride
我们描述了一种新的不对称方法,使用Staudinger化学方法对脯氨酸衍生的螺-β-内酰胺类化合物进行了研究。脯氨酸的酰基氯的C-4上的手性基团指导Staudinger化学的立体选择性,随后被牺牲以获得具有光学活性的5.4-螺-β-内酰胺。还讨论了施陶丁格化学的4-烷基(芳基)磺酰氧基-1-脯氨酸酰氯与亚胺的斯道丁格化学的观察结果的范围,局限性和机理原理。
