该中间体在本合成路线中的序号：(III)Treatment of 2,2'-dithiobis(benzoic acid) (I) with thionyl chloride produced the corresponding acid chloride (II), which was further condensed with thiazolidine-2-carboxylic acid (III) in the presence of Na2CO3 to furnish diamide (IV). Reductive cleavage of the disulfide group of (IV) by means of NaBH4 in refluxing EtOH yielded thiol (V). Finally, intramolecular cyclization of (V) to give the title tricyclic compound was achieved by treatment with carbonyl diimidazole in boiling THF.
