regioselective ring-opening reaction of epoxides with various carboxylic acids under metal-free conditions is reported. The ring-opening of epoxides takes place in the presence of graphite oxide as an efficient and available catalyst to produce the corresponding 2-hydroxy monoester and 1,2-diester derivatives in good yields. Regioselective attack of the nucleophile, short reaction times, metal-free conditions
据报道,在无金属条件下,环氧化物与各种羧酸的有效,简单和区域选择性的开环反应。环氧化物的开环发生在作为有效和可用催化剂的氧化石墨存在下,以高收率生产相应的2-羟基单酯和1,2-二酯衍生物。亲核试剂的区域选择性攻击,较短的反应时间,无金属条件和催化剂的可重复使用性是本方案的优点。
