Reaction Steps

To 0.36 g (2.1 mmol) of 2-(trimethoxy)silyl-1,3-butadiene [II], were added 0.19 g (1.9 mmol) of maleic acid anhydride [III]at room temperature and stirred for one hour. After the reaction was over, the reaction product was separated on chromotography using silica gel and developing with a mixed solvent of n-hexane-diethyl ether to obtain 0.44 g of 4-(trimethoxy)silyl-1,2,3,6-tetrahydrophthalic acid anhydride [I](yield: 80 %, liquid).
