aromatic hydrocarbons and substituted phenolic derivatives with dimethoxymethane and chlorosulfonic acid was carried out in the presence of 10 mol% of ZnCl2 in a mild and efficient manner under solvent-free conditions. In addition, 2,6-dimethyltyrosine was synthesized in high yield via this protocol. GRAPHICAL ABSTRACT
摘要 在无溶剂条件下,在 10 mol% ZnCl2 存在下,以温和高效的方式,用二甲氧基甲烷和氯磺酸对各种芳烃和取代酚类衍生物进行氯甲基化反应。此外,通过该协议以高产率合成了 2,6-二甲基酪氨酸。图形概要
