合成路线1
该中间体在本合成路线中的序号:(I)The cyclization of the benzoic ester (I) with phenylacetylene (II) by means of triethylamine in THF gives the diphenyl isoxazole (III), which is hydrolyzed with NaOH in ethanol/THF yielding 4-[5-(4-pentyloxyphenyl)isoxazol-3-yl]benzoic acid (IV). The activation of (IV) with HOBT and WSC in dichloromethane affords the benzotriazol-1-yl ester (V), which is finally condensed with the cyclic peptide (VI) by means of DMAP in DMF.
