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.
阳离子杂芳族烯炔首次在乙烯气氛下并使用Hoveyda-Grubbs催化剂作为烯炔闭环复分解的底物。反应得到新的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生物学上相关的阳离子的有用前体。
