An atom economical and environmentally benign protocol has been developed for the regioselective C(sp2)–H bond functionalization of indolizines. The acetic acid-catalyzed cross-coupling reaction proceeds under metal-free conditions, producing a wide range of synthetically useful indolizine derivatives. The present protocol showed good functional group tolerance and broad substrate scope in good to
已经为区域选择性 C(sp 2 ) 开发了一种原子经济和环境友好的协议)–中氮茚的H键官能化。乙酸催化的交叉偶联反应在无金属条件下进行,产生多种合成有用的中氮茚衍生物。本协议表现出良好的官能团耐受性和广泛的底物范围,产量良好。使用密度泛函理论 (DFT) 进行的量子力学研究在了解乙酸是确定作为催化剂的实际途径及其超快性质的关键因素方面发挥了至关重要的作用。研究了涉及分子间和分子内质子转移的不同途径,有或没有乙酸。计算结果表明,质子穿梭机制涉及能量最低、最有利的乙酸催化途径。此外,
