该中间体在本合成路线中的序号：(LXIII)Hydrogenolysis of the benzyl ether of (LIX) and subsequent treatment with Tf2O gave aryl triflate (LX). Stille coupling reaction of (LX) with organotin reagent (LXI) produced unsaturated ester (LXII), which was then hydrogenated over Pd/C to give (LXIII). Basic hydrolysis of both ester groups of (LXIII) yielded the racemic diacid, which was finally resolved using quinidine.
