合成路线1
该中间体在本合成路线中的序号：(XX)Alternatively, the reaction of the cyclic sulfate (VIII) with potassium phthalimide (XVIII) gives the N-substituted phthalimide (XIX), whose sulfate group is cleaved with sulfuric acid to yield the alcohol (XX). The reaction of (XX) with the perhydroisoquinoline (XV) by means of K2CO3 in acetonitrile/methanol affords the oxazoline (XXI), whose ring is opened with thiophenol (XVII) and KHCO3 in THF, providing a mixture of the two sulfides (XXII) and (XXIII) that are not isolated. The cleavage of the phthalimido group with refluxing ethanolamine followed by a treatment with benzoic acid gives a mixture of ammonium salts that is separated by crystallization, yielding the desired isomer (XXIV). The reaction of (XXIV) with acid chloride (XII) affords the precursor (XXV), which is finally deacetylated with NaOH to provide the target compound.
