phenyl-o-phenylene borate (a double activation technique), is reported. Further, this new method with broad functional group compatibility was extended to a one-pot/two-step synthesis of chiral benzoxazine and quinoxaline derivatives.
通过使用Pd(0)和苯基-o生成的π-烯丙基钯-硼酸酯络合物的胺化反应,从乙烯基环氧化物合成1,2- syn-vic氨基醇(具有双重构型)的新方法报道了硼酸亚苯基酯(双重活化技术)。此外,这种具有广泛的官能团相容性的新方法扩展到手性苯并恶嗪和喹喔啉衍生物的一锅/两步合成。
