have been produced via kinetic resolution of racemic mefloquine using a ROMP‐gel supported chiral acyl hydroxamic acid resolving agent. The requisite monomer was prepared in a few synthetic steps without chromatography and polymerization was safely performed on a >30 gram scale under ambient conditions. The reagent was readily regenerated and reused multiple times for the resolution of 150 grams of (±)‐mefloquine
使用ROMP-gel负载的手性酰基异羟肟酸拆分剂,通过消旋外消旋甲氟喹的动力学拆分,制得了十克量的对映纯(+)-甲氟喹。通过几个合成步骤无需色谱即可制备所需的单体,并且在环境条件下以大于30克的规模安全地进行聚合。该试剂易于再生,可多次重复使用,分离出150克(±)-甲喹和其他手性N-杂环基。
