An operatically simple method for the ethynylation of isoquinolines and quinolines is described. The ionic adduct derived from an alkynoic ester and the N-heterocycle was attacked by calcium carbide to give the ethynylation product. The procedure uses tetrabutylammonium fluoride trihydrate as a catalyst in aqueous N , N -dimethylacetamide. Steric and electronic effects of various substituents on the
描述了一种操作简单的异喹啉和喹啉乙炔化方法。衍生自炔酸酯和 N-杂环的离子加合物受到碳化钙的攻击,得到乙炔化产物。该程序使用四丁基氟化铵三水合物作为催化剂在 N, N-二甲基乙酰胺水溶液中。检查了各种取代基对反应结果的空间和电子效应。
