The Rh(iii)-catalyzed synthesis of spiroquinoxalinone derivatives from 3-arylquinoxalin-2(1)-ones and alkynes a C-H functionalization/[3 + 2] annulation sequence has been developed. This method, featuring low catalyst loading, was amenable to Gram scale synthesis and tolerated a variety of functional groups and substitution patterns on the aryl rings, providing the target products in good to excellent yields.
已开发出一种由铑（III）催化的、从3-芳基喹喔啉-2（1）-酮和炔烃合成螺喹喔啉酮衍生物的方法，该方法是一种C-H官能团化/[3+2]环化序列。此方法催化剂负载量低，适用于克级规模的合成，并且能耐受芳环上的各种官能团和取代模式，以良好至优异的产率提供目标产物。
