合成路线1
该中间体在本合成路线中的序号：(V)Treatment of (R,R)-1,2-diaminocyclohexane (I) with triphenylmethyl chloride produced the N-trityl derivative (II). Subsequent condensation of (II) with glyoxal (III) gave the bis-imine (IV), which was reduced to amine (V) using LiBH4. Cleavage of the N-trityl groups of (V) with HCl in acetone afforded tetraamine (VI). This was then condensed with 2,6-diacetylpyridine (VII) in the presence of MnCl2 to furnish the cyclic bis-imine manganese complex (VIII). Finally, transfer hydrogenation of the imine functions of (VIII) using ammonium formate and Pd/C produced the cyclic pentaamino derivative as a diastereomeric mixture. The title isomer was then purified by separative partition between H2O and CH2Cl2.
