合成路线1
该中间体在本合成路线中的序号：(FR-179642)The synthesis of FK-463 can be performed as follows: The enzymatic deacylation of FR-901379 with Streptomyces anulatas No. 4811, S. anulatas No. 8703, Streptomyces strain No. 6907 or A. utahensis IFO13244 gives the deacylated lipopeptide FR-179642 (1), which is then reacylated with 1-[4-[5-(4-pentyloxyphenyl)isoxazol-3-yl]benzoyl]benzotriazole 3-oxide (VI) by means of dimethylaminopyridine (DMAP) in DMF. The acylating compound (VI) can be obtained as follows: The cyclization of 4-pentyloxyphenylacetylene (I) with 4-(hydroxyiminomethyl)benzoic acid methyl ester (II) by means of triethylamine in hot THF gives 4-[5-(4-pentyloxyphenyl)isoxazol-3-yl]benzoic acid methyl ester (III), which is hydrolyzed with NaOH in hot THF/water yielding the corresponding free acid (IV). Finally, this compound is condensed with 1-hydroxybenzotriazole (V) by means of 1-ethyl-3-[3-(dimethylamino)propyl]carbodiimide (EDMCA) in dichloromethane.
