合成路线1
该中间体在本合成路线中的序号:(VII)Alkylation of N-Boc-4-(R)-hydroxyproline (I) with 2-(bromomethyl)-naphthalene (II) in the presence of NaH afforded the (naphthylmethyl) ether (III). N-Boc-norvaline (IV) was converted to the benzyl ester (V) by treatment with benzyl bromide and DBU. Subsequent acid cleavage of the Boc group of (V) yielded norvaline benzyl ester (VI). This was coupled with proline derivative (III) using HATU to give the protected dipeptide (VII).
