摘要:
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.
