PROCEDURE

实验过程

The crude alcohol, {(1S,5R,6R,7R)-6-[(1E,3R,4R)-3-hydroxy-4-(m-tolyl)-1-pentenyl]-7-benzoyloxy-2-oxabicyclo[3.3.0]octan-3-one} (649.9 g) synthesized in Example 4 was dissolved in methanol (740 mL), potassium carbonate (116.3 g) was added, and the mixture was stirred at room temperature for 17 hr. Acetic acid was added to adjust to pH 7, methanol was evaporated, water was added, and the mixture was extracted with ethyl acetate. The extract was purified by silica gel column chromatography (hexane/ethyl acetate=4/1-0/1) to give the title compound (22.3 g). The structural property was as described below.
