PROCEDURE

实验过程

A solution of 16.58 g of (1S,5R,6S,7R)-7-benzoyloxy-6-hydroxymethyl-2-oxabicyclo[3.3.0]octan-3-one in 18 ml of dimethylformamide is combined at 0° C. with 10.21 g of imidazole and 10.85 g of tert.-butyldimethylsilyl chloride. The mixture is stirred for 24 hours at 20° C., diluted with 1.5 l of ether, shaken in succession with 5% sulfuric acid and brine, dried over magnesium sulfate, and evaporated under vacuum. The residue is recrystallized from hexane.
