The gold-catalyzed cycloisomerizations of 1,6-ene-ynamides proceed under mild conditions and lead to cyclobutanones from terminal or trimethylsilyl substituted ynamides, or to carbonyl compounds bearing a 2,3-methanopyrrolidine subunit from substrates possessing a propargylic alcohol moiety. High diastereoselectivities are observed with 1,6-ene-ynamides having a stereocenter at the α or β position
1,6-烯-酰胺的金催化的环异构化在温和的条件下进行,并从末端或三甲基甲硅烷基取代的酰胺中产生环丁酮,或从具有炔丙醇部分的底物上产生带有2,3-甲基吡咯烷亚基的羰基化合物。用在氮原子的α或β位置具有立体中心的1,6-烯-酰胺具有高的非对映选择性。
