The reactions of oxazolidone 1 with N-benzylimines proceed with exceptional levels of asymmetric induction to form the cycloadducts 2. Subsequent dissolving metal reduction affords the homochiral β-lactam derivatives 3 in good overall yield (eq 1).
恶唑烷酮1与N-苄基亚胺的反应以异常水平的不对称诱导进行,以形成环加合物2。随后的溶解金属还原以良好的总收率(eq 1)提供了同手性的β-内酰胺衍生物3。
