合成路线1
该中间体在本合成路线中的序号:(XXVIe)1) By condensation of benzhydryl (6R,7R)-7-amino-7-methoxy-3-[[(1-methyl-1H-1,2,3,4-tetraazol-5-yl)sulfanyl]methyl]-8-oxo-5-oxa-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate (XXIV) with alpha-diphenylmethoxycarbonyl-alpha-(p-hydroxyphenyl)acetic acid (XXVa) by means of Et3N and oxalyl chloride in methylene chloride gives the 7-[alpha-diphenylmethoxycarbonyl-alpha-(p-hydroxyphenyl)acetamido]-7alpha-methoxy compound (XXVIa). Finally, all the protecting groups of (XXVIa) are eliminated by treatment with trifluoroacetic acid in anisole. 2) Compound (XXIV) can also be condensed with alpha-(p-benzyloxyphenyl)malonic acid monobenzyl ester (XXVb) by means of Et3N and oxalyl chloride in methylene chloride yielding the 7beta-[alpha-(p-benzyloxyphenyl)-alpha-benzyloxycarbonylacetamido]-7alpha-methoxy compound (XXVIb), which is hydrolyzed with trifluoroacetic acid in anisole. 3) Compound (XXIV) can also be condensed with alpha-(p-methoxybenzyl)oxycarbonyl-alpha-[p-(p-methoxybenzyl)oxyphenylacetic acid (XXVc) by means of Et3N and oxalyl chloride in methylene chloride giving the corresponding derivative (XXVIc), which can be hydrolyzed with trifluoroacetic acid in anisole. 4) Finally, compound (XXIV) can also be condensed with p-(p-methoxybenzyloxy)phenylmalonic acid (XXVd) by means of Et3N and oxalyl chloride in methylene chloride affording compound (XXVId), which is hydrolyzed with trifluoroacetic in anisole. 5) Compound (XXIV) can also be condensed with alpha-diphenylmethoxycarbonyl-p-(p-methoxybenzyl)oxyphenylacetic acid (XXVe) by means of Et3N and oxalyl chloride in methylene chloride affording the corresponding derivative (XXVIe), which is hydrolyzed with trifluoroacetic acid in anisole.
