PROCEDURE

实验过程

Trifluoromethanesulfonic anhydride (10.57 g) was added to a solution of methyl (E) 6-(1,3-dihydro-6-hydroxy-7-methyl-3-oxo-4-p-toluenesulfonyloxyisobenzofuran-5-yl)-4-methyl-4-hexenoate in methylene chloride (500 ml) amd pyridine (5 ml) at 0° C. After 6 hours the reaction was added to excess aqueous sodium bicarbonate. The organic solution was dried and evaporated to afford methyl (E) 6-(1,3-dihydro-7-methyl-3-oxo-4-p-toluenesulfonyloxy-6-trifluoromethanesulfonyloxyisobenzofuran-5-yl)-4-methyl-4-hexenoate.
