Three-component reactions of cotarnine chloride with silver acetylides and methyl propiolate or ethynyl methyl ketone in acetonitrile, as well as two-component reactions of 5-phenylethynyl-substituted tetrahydro[1,3]dioxolo[4,5-g]isoquinoline with alkynes in various solvents were studied. Performing them in 2,2,2-trifluoroethanol as the solvent, 10-phenylethynyl-substituted tetrahydro[1,3]dioxolo[4
乙炔基氯化银与乙炔化银和丙酸甲酯或乙炔基甲基酮的三组分反应,以及5-苯基乙炔基取代的四氢[1,3]二氧戊并[4,5- g ]异喹啉与炔烃的二组分反应在各种溶剂中进行了研究。在2,2,2-三氟乙醇为溶剂中进行合成,可得到高产率的10-苯基乙炔基取代的四氢[1,3]二氧代[4,5- i ]-[3]苯甲唑啉。
