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
