A series of (R)-(+)-ethyl aryloxypropionates (4a–4p) have been synthesized by the reaction of substituted phenols with ethyl (S)-(−)-tosyloxy lactate under the conditions of microwave irradiation and without solvents. The reaction conditions have been optimized. A good method for the preparation of (R)-(+)-ethyl aryloxypropionate was developed, with good yields, high enantiomer excess, short reaction
在微波辐射和无溶剂条件下,通过取代苯酚与 (S)-(-)-甲苯磺酰氧基乳酸乙酯反应合成了一系列 (R)-(+)-乙基芳氧基丙酸酯 (4a-4p)。优化了反应条件。开发了一种制备(R)-(+)-乙基芳氧基丙酸酯的良好方法,具有收率好、对映体过量高、反应时间短、后处理容易、操作简单等优点。
