new synthetic methodology for preparing cyclopropanes is presented. The reaction involves a cooperative zirconium- and Lewis acid-mediated deoxygenative coupling of carbonyl compounds with a Grignard reagent. In this way, various cyclopropanes are obtained in moderate to excellent yields, directly from saturated, unsaturated, and aromatic aldehydes and ketones. This reaction tolerates the presence of
提出了一种制备环丙烷的新合成方法。该反应涉及羰基化合物与格氏试剂的协同锆和路易斯酸介导的脱氧偶联。通过这种方式,可以直接从饱和、不饱和和芳香族醛和酮中以中等至极好的收率获得各种环丙烷。该反应允许存在几种不同的官能团。
