合成路线1
该中间体在本合成路线中的序号：(XXVIII)A convergent synthesis was further developed. Azide (XII) was reduced to the corresponding amine (XXVIII) employing triethyl phosphite. Hydrolysis of the thioacetate ester of (XXVIII) then gave thiol (XXIX). Coupling of (XXIX) with protected valine succinimidyl ester (XXVI) produced amide (XXX). Condensation of (XXX) with carbapenem phosphate (VIII) yielded adduct (XXXI). The p-nitrobenzyl esters were finally deprotected by catalytic hydrogenation.
