Total Synthesis of d,l-Methynolide. Sulfur Removal and Remote Stereocontrol

The details for the conversion of 1 into d,l-methynolide are described.Key steps include the highly selective reduction to alcohol 3, the oxidation α to sulfide sulfur from 3 to thiolactone 13, and the acyl transfer from 14 to the lactone 16.Photochemical
