Reaction Steps

Ethyl (2-methylene-3,4-dihydroxy-5-(tert-butyldiphenylsilyloxy)cyclohexylidene)acetate (0.466 g) was dissolved in 5 ml of methylene chloride, and 0.204 g of imidazole and 0.30 g of tert-butyldiphenylsilyl chloride were added, followed by stirring the mixture at room temperature for 3 hours. The reaction mixture was poured into water, and extracted with diethyl ether. The extract was washed with a saturated sodium chloride aqueous solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give 0.664 g of ethyl (3,5-bis-(tert-butyldiphenylsilyloxy)-4-hydroxy-2-methylene-cyclohexylidene)acetate having the following property.
