derived and binaryphasediagrams were reconstructed for the whole family. Solid racemic compounds stabilities were ranked for the four substances. Spontaneous resolution was established for the registered chiral drug mephenesin and its ethyl analogue. Metastable anomalous conglomerate, forming crystals having three independent R* and one independent S* molecules in the unit cell, is formed during solution

A number of 3-aryloxypropanedioles were obtained by treating glycidol with phenols. The latter with thionyl chloride afforded 4-aryloxymethyl-1,3,2-dioxathiolane 2-oxides. These compounds were also obtained from 4-chloromethyl-1,3,2-dioxathiolane 2-oxides by substitution aryloxy group for chlorine. The cyclic sulfides synthesized are universal intermediates in the synthesis of chiral aryloxypropanolamines among which are known beta-adrenoblockaders, cardiovascular drugs. From (S)-glycidol, (S)-alprenolol, (S)-propanolol, and (S)-thymolol were synthesized.
