Abstract
An enantiospecific synthesis of cyclohexane-1,2,3,4-tetrols was accomplished from l-(+)-tartaric acid. Pivotal steps in the synthetic sequence include zinc-mediated Boord-type fragmentation of an acetonide, ring-closing metathesis (RCM), and osmium-mediated dihydroxylation.
Key words
cyclitols - ring-closing metathesis - tartaric acid - Boord fragmentation
