Abstract
An unusual rhodium carbenoid approach for introduction of 4-substituted (Z)-pent-2-enoates into sterically encumbered pyrroles and indoles is described. These studies show that (Z)-vinylcarbenoids have a greater tendency than (E)-vinylcarbenoids to react at the vinylogous position of the carbenoid rather than at the carbenoid center.
摘要
描述了一种将 4-取代的（Z）-戊-2-烯酸酯引入空间位阻较大的吡咯和吲哚中的铑卡宾的不寻常方法。这些研究表明，（Z）-乙烯基卡宾比（E）-乙烯基卡宾更倾向于在卡宾的烯丙位而不是卡宾中心反应。
