microsomal epoxide hydrolase is entirely regiospecific and involves in both cases exclusive attack at C-4. The racemic cis-epoxide reacts at a faster rate than the trans. The 2R,3R,4S-enantiomer of the latter epoxide reacts at a much faster rate than its antipode to yield the (–)-(2R,3R,4R)-diol which is isolated at least 98% optically pure up to almost 50% conversion when starting from the racemic substrate
