Another pathway: A new type of Lewis acid promoted [3+3] cycloaddition of methylenecyclopropane‐1,1‐diesters with C,N‐diarylnitrones is disclosed. This cycloaddition is highly site‐, regio‐, and stereoselective and proceeds in moderate‐to‐excellent yields. A three‐component one‐pot version of the cycloaddition is also reported.
另一途径:公开了一种新型的路易斯酸促进了亚甲基环丙烷-1,1-二酯与C,N-二芳基硝酮的[3 + 3]环加成反应。这种环加成反应具有很高的位点,区域和立体选择性,产率中等至优异。还报告了三组分一锅法的环加成反应。
