Two highly efficient protocols for the regioselective synthesis of 2-substituted 4-alkenyl- and 4-aryl-1,2,3-triazoles by the palladium-catalyzed C–H functionalization of 1,2,3-triazole N-oxides are reported. A possible pathway of direct alkenylation with 1-octene and vinyl acetate is discussed.
据报道,通过
钯催化
1,2,3-三唑N-氧化物的C-H官能化,可以高效地合成2-取代的4-烯基和4-芳基
1,2,3-三唑的两种高效方法。讨论了用1-
辛烯和
乙酸乙烯酯进行直接烯基化的可能途径。
