for metal-, photocatalyst-, and light-free Minisci C–H alkylation reactions of N-heteroarenes with alkyl oxalates derived from primary, secondary, and tertiary alcohols. The protocol uses environmentally benign persulfate as a stoichiometric oxidant and does not require high temperatures or large excesses of either of the substrates, making the procedure suitable for late-stage C–H alkylation of complex
在此,我们报告了N-杂芳烃与衍生自伯醇、仲醇和叔醇的草酸烷基酯的无金属、光催化剂和无光 Minisci C-H 烷基化反应的温和方案。该协议使用对环境无害的过硫酸盐作为化学计量氧化剂,不需要高温或任何一种底物的大量过量,使得该程序适用于复杂分子的后期 C-H 烷基化。值得注意的是,可以使用该协议对几种药物和天然产品进行功能化或制备,从而证明其实用性。
