Reaction Steps
A solution of 1.0 g of (S,S)-2,4-dibenzylglutaric anhydride and 0.54 g of 4-hydroxymethyl-2,2-dimethyl-1,3-dioxolane in 10 ml of toluene is refluxed overnight. The solution is washed with water, dried (Na2SO4), filtered and concentrated to give 4-[(2,2-dimethyl-1,3-dioxolan-4-yl)-methoxycarbonyl]-(S,S)-2,4-dibenzylbutyric acid as a viscous oil.
