Synthetic study on 1,3-polyols. An efficient enantioselective synthesis of tarchonanthuslactone
Abstract
Tarchonanthuslactone, a syn-1,3-polyol-derived α,β-unsaturated δ-lactone, has been synthesized. The coupling reaction of a chiral dithiane with a chiral epoxide and highly syn-stereoselective 1,3-asymmetric reduction of the derived hydroxy ketone led to the synthesis of tarchonanthuslactone in a stereocontrolled manner.
