β-Lactams were prepared from imines and aryl-substituted acetic acids using T3P as an activating agent. In most cases, good to excellent yields were obtained (up to 93%) and the trans-β-lactam was the exclusive or major diastereoisomer (confirmed through analysis of 1H NMR coupling constants and by X-ray crystallography).
使用T3P作为活化剂,由亚胺和芳基取代的乙酸制备β-内酰胺。在大多数情况下,可获得良好至优异的收率(高达93%),反式-β-内酰胺是唯一或主要的非对映异构体(通过1 H NMR偶合常数分析和X射线晶体学证实)。
