N-杂环卡宾(NHC)催化的转化已经成为构建复杂分子的有力策略。自从Stetter在1975年报道通过使用卡宾催化全合成顺式茉莉酮和二氢茉莉酮以来,NHC在全合成中的使用迅速增长,特别是在过去十年中。这种复兴无疑是由于NHC催化反应的最新发展,包括新的安息香,Stetter,homoenolate和aroylation过程。这些转换采用典型的以及Umpolung类型的键断,并已在几个新的全合成的关键步骤。这篇迷你评论突出了这些报道,并抓住了卡宾催化在全合成中的兴奋和新兴的合成效用。
N-Heterocyclic carbene (NHC) catalyzed transformations have emerged as powerful tactics for the construction of complex molecules. Since Stetter’s report in 1975 of the total synthesis of cis-jasmon and dihydrojasmon by using carbene catalysis, the use of NHCs in total synthesis has grown rapidly, particularly over the last decade. This renaissance is undoubtedly due to the recent developments in NHC-catalyzed reactions, including new benzoin, Stetter, homoenolate, and aroylation processes. These transformations employ typical as well as Umpolung types of bond disconnections and have served as the key step in several new total syntheses. This Minireview highlights these reports and captures the excitement and emerging synthetic utility of carbene catalysis in total synthesis.
