合成路线1
该中间体在本合成路线中的序号：(VII)Synthetic pathway for obtaining EN 292685: Treatment of amino acid (I) with CbzOSu affords the protected amino acid (II), which is further protected by means of Boc2O to yield derivative (III). Condensation of amino acid (III) with N,O-dimethyl hydroxylamine by means of BOP and DIEA provides hydroxamic ester (IV), which is then subjected to hydrogenolysis over Pd/C in CHCl3 for selective deprotection, furnishing compound (V). Coupling of (V) to intermediate (VI) affords derivative (VII), which is then coupled to lithium derivative (VIII) to give protected compound (IX). Finally, the Boc group of (IX) is removed by treatment with TFA.
