摘要

Abstract Bicyclobis (γ-butyrolactone)(BBL) bearing methyl group 1a reacted with benzyl alcohol (BnOH) in the presence of p-toluenesulfonic acid (p-TsOH) through the double ring- opening of the bislactone structure to afford the corresponding adduct 2a bearing carboxyl group. The resulting carboxyl group underwent condensation with BnOH to afford the corresponding diester 3a. The second step was quite slow at ambient temperature; ...
