该中间体在本合成路线中的序号：(III)Condensation of the Weinreb amide of N-Boc-proline (I) with the lithium anion of benzothiazole (II) in THF at -78 C gave benzothiazolyl ketone (III), which was reduced with NaBH4 to afford the diastereomeric mixture of alcohols (IV). Deprotection of the Boc group of (IV) by means of HCl in EtOAc provided pyrrolidine (V). This was then coupled with Z-leucyl-glycine (VI) in the presence of PyBOP to give the peptidyl alcohol (VII). Finally, Swern oxidation of (VII) furnished the corresponding ketone.
