Cationic heteroaromatic enynes have been employed as substrates in enyne ring-closing metathesis, under an atmosphere of ethylene and using the Hoveyda-Grubbs catalyst, for the first time; the reaction affords new 1-vinyl- and 2-vinyl-substituted 3,4-dihydroquinolizinium salts, useful precursors for biologically relevant cations based on the quinolinizium system.
首次在乙烯气氛下，使用霍维达-格鲁布斯催化剂，将阳离子杂芳基烯炔用作烯炔闭环复分解反应的底物；该反应得到了新的1-乙烯基和2-乙烯基取代的3,4-二氢喹啉鎓盐，它们是基于喹啉鎓体系的与生物相关的阳离子的有用前体。
