On catalysis by trimethylsilyl trifluoromethane-sulphonate, 4-acetoxy-1-trimethylsilylazetidin-2-one reacted with the enol silanes [R1CHC(OSiMe3)R2] to give the β-lactams [[graphic omitted]HCH(R1)COR2] in excellent yields (71 to 95%).
在三甲基甲硅烷基三氟甲烷磺酸酯的催化下,4-乙酰氧基-1-三甲基甲硅烷基氮杂环丁烷-2-one与烯醇硅烷[R 1 CH C(OSiMe 3)R 2 ]反应,得到β-内酰胺[[略图] HCH(R)1)COR 2 ],收率极高(71%至95%)。
