A short, formal synthesis is reported for pentalenene. The key steps are copper-catalyzed 1,4-addition of isobutylmagnesium bromide to a cyclooctenone derivative, enolate alkylation with the thiocarbene complex [(η5-C5H5)(CO)2Fe=CHSPh]+ PF6−, and cyclopentane ring formation by means of intramolecular C-H insertion, leading to a late intermediate in a previously reported synthesis of pentalene.
据报道,戊烯是一种简短的正式合成方法。的关键步骤是铜催化1,4-加成异丁基溴化镁的一种cyclooctenone衍生物,烯醇化物烷基化与thiocarbene络合物[(η 5 -C 5 H ^ 5)(CO)2的Fe = CHSPh] + PF 6 - ,和通过分子内CH插入形成环戊烷环,导致先前报道的戊烯合成中的晚期中间体。
