合成路线1
该中间体在本合成路线中的序号：(V)Reaction of the labeled chiral bromoacetylbornanesultam (I) with benzophenone imine (II) and DIEA in hot acetonitrile gives the imine (III), which is enantioselectively alkylated with isopropyl iodide and n-BuLi yielding the L-valine derivative (IV). Treatment of (IV) with HCl in THF in order to eliminate the diphenylmethylene group affords compound (V) with a free amino group that by protection with Boc2O in THF provides the L-valine derivative (VI). The hydrolysis of (VI) with LiOH in THF/water affords labeled N-(tert-butoxycarbonyl)-L-valine (VII), which is condensed with the decapeptide (VIII) by means of BOP and NMM in dichloromethane providing the linear undecapeptide (IX).
