该中间体在本合成路线中的序号:(VI)

Orcinol (I) is first derivatized to (III) by reaction with sulfonyl chloride (II) in a mixture of aqueous NaHCO3 (sat) and Et2O. Monosulfonate (III) undergoes Mitsunobu reaction with monobenzylated diol (IV) in the presence of PPh3 and DEAD in dichloromethane to yield derivative (V), which is then debenzylated by hydrogenolysis over Pd/C in MeOH, or in THF/HCl/dioxane, to afford (VI). Alcohol (VI) is oxidized with SO3·pyr complex in DMSO/dichloromethane in the presence of DIEA to provide aldehyde (VIII), which finally reacts with aminoguanidine nitrate in EtOH in the presence of HCl/dioxane.

合成路线2

该中间体在本合成路线中的序号:(VI)

2-Chlorobenzenesulfonyl chloride (I) was coupled to orcinol (II) to give sulfonate (III). Subsequent condensation of (III) with 3-benzyloxypropanol (IV) under Mitsunobu conditions afforded ether (V). After hydrogenolytic deprotection of the benzyl group, Swern oxidation of the resulting alcohol (VI) with DMSO and SO3-pyridine complex provided aldehyde (VII). The title amidinohydrazone was then obtained by treatment of (VII) with aminoguanidine nitrate (VIII).
