The reaction of 2,5-dimethoxytetrahydrofuran-3-carbaldehyde (I) with 2-(trimethylsilyl)-1,3-dithiane (II) by means of BuLi in THF gives the expected condensation product (III), which is treated with HgCl2 and methanol in THF/water yielding 2-(2,5-dimethoxytetrahydrofuran-3-yl)acetic acid methyl ester (IV). The cyclization of (IV) with 4'-aminobiphenyl-4-carbonitrile (V) by means of CDE in hot trifluorocetic acid affords the biphenylylpyrrole (VI), which is hydrolyzed with LiOH and condensed with the chiral auxiliary 4(S)- benzyloxazolidin-2-one (VII) by means of pivaloyl chloride, BuLi and TEA in THF giving the acylated thiazolidine (VIII). The stereocontrolled reaction of (VIII) with benzyl bromoacetate (IX) by means of sodium hexamethyldisylazane (NaHMDS) in THF yields the succinamic ester (X), which is hydrolyzed with LiOH in THF/water to afford the succinic acid monoester (XI). The amidation of (XI) with 3(S)-amino-4,4-dimethyltetrahydrofuran-2-one (XII) by means of TBTU and NMM in DMF provides the succinamic ester derivative (XIII), which is debenzylated by hydrogenation with H2 over Pd/C in methanol.
