N-Benzyloxyimines have been shown to react with ketene silyl acetals in the presence of trimethylsilyl triflate catalyst to give alkyl β-benzyloxyaminocarboxylates. Conversion of them to β-lactams has been exemplified.
已显示在三氟甲磺酸三甲基甲硅烷基酯催化剂存在下,N-苄氧基氧亚甲基与乙烯酮甲硅烷基缩醛反应,生成烷基β-苄氧基氨基羧酸酯。已经举例说明了它们向β-内酰胺的转化。
