A N-Heterocyclic carbenes (NHC) catalyzed vinylogous aldol reaction between 2-(trimethylsilyloxy)furan and aldehydes has been developed, providing γ-substituted butenolides in high yields with good diastereoselectivities. Furthermore, the catalyst loading can be reduced to 1 mol%.
一种N-杂环卡宾(NHC)催化的2-(三甲基硅氧基)呋喃与醛的乙烯式醇醛反应已经开发出来,能够在高产率和良好的非对映选择性下提供γ-取代的丁烯内酯。此外,催化剂负载量可降至1摩尔%。
