Abstract

Abstract The enantioselective partial hydrolysis of a number of racemic aryl glycidyl ethers in the presence of chiral Co (salen)-catalyst was studied. The enantiomeric composition of the isolated (R)-aryl glycidyl ethers was analyzed by 31 P NMR using optically active substituted 2-chloro-1, 3, 2-dioxaphospholanes. A synthesis of β-adrenoblocking agents (S)-toliprolol and (S)-moprolol based on the simultaneously obtained (S)-3-aryloxypropane-1, 2-diols ...
