该中间体在本合成路线中的序号:(XXXVI)

A more direct procedure was based on the activation of the unprotected disaccharide acid (XXXVI) as the pentafluorophenyl ester (XXXVII) by treatment with bis(pentafluorophenyl) carbonate. Active ester (XXXVII) was subsequently coupled with L-alanyl-D-isoglutamine (XXXVIII) to afford the corresponding amide.

该中间体在本合成路线中的序号:(XXXVI)

The disaccharide derivative (XXXVI) was isolated from the enzymatic hydrolysis of the cell walls obtained from cultures of Micrococcus lysodeikticus. Condensation of (XXXVI) with L-alanyl-D-isoglutamine benzyl ester (XIV), by means of N-ethyl-5-phenylisoxazolium-3'-sulfonate (NEPIS, Woodward's reagent K) as the coupling reagent, furnished amide (XLIX). The benzyl ester group of (XLIX) was finally cleaved by hydrogenolysis over Pd/C.

合成路线3

该中间体在本合成路线中的序号:(XXXVI)

The precursor N-acetylglucosaminyl-N-acetylmuramic acid (XXXVI) was obtained by an alternative route. The protected glucosamine acid (L) was esterified with benzyl alcohol in the presence of EDC and DMAP to yield the benzyl ester (LI). The 4,6-O-benzylidene group of (LI) was then subjected to reductive cleavage with NaBH3CN, producing the 6-O-benzyl-4-hydroxy derivative (LII). Coupling of (LII) with the thioglucoside (LIII) was accomplished in the presence of nitrosyl tetrafluoroborate, to afford (LIV). Depththaloylation and hydrolysis of (LIV) with methanolic butylamine provided (LV). Then, amino group acetylation with Ac2O in MeOH gave amide (LVI). The O-benzyl protecting groups of (LVI) were then removed by catalytic hydrogenation, leading to precursor (XXXVI).
