By Suzuki cross-coupling reaction of peurutenicin triflate with arylboric, furanylboric, pyridinylboric, and indolylboric acids the corresponding 7-aryl(hetaryl)coumarins were synthesized. The high activity of hetaryl-substituted boric acids in the Suzuki reaction was observed. Heck reaction of 7-O-trifluoromethylsulfonylpeur utenicin with terminal olefins (styrene, vinylpyridines, vinylpyrazine, vinyltriazole)
通过铃木酸泛酸泛酸菌素与芳基硼酸,呋喃基硼酸,吡啶基硼酸和吲哚基硼酸的Suzuki交叉偶联反应,合成了相应的7-芳基(杂芳基)香豆素。在铃木反应中观察到杂芳基取代的硼酸的高活性。使用7- O-三氟甲基磺酰普联素与末端烯烃(苯乙烯,乙烯基吡啶,乙烯基吡嗪,乙烯基三唑)的Heck反应制备(E)-7- [芳基(杂芳基)乙烯基]香豆素。发现反应产物产率对催化体系性质的依赖性。
