Procedure

To a solution of (1S,5R,6R,7R)-6-(3,3-ethylenedioxyoctyl-7-(4-phenylbenzoyloxy)-2-oxabicyclo[3.3.0]octan-3-one (5a) (8.20 g) in methanol (200 ml) was added potassium carbonate (1.15 g) and the resultant mixture was stirred overnight, and acetic acid (1 ml) was added thereto. The crude product obtained by treating in the conventional manner was subjected to silica gel column chromatography to give the title compound (6a).
