The reaction of 2-(1-imidazolyl)acetonitrile (I) with CS2 and KOH in DMF gives the dithiolate (II), which is then cyclized with 1-(2-chlorophenyl)-1,2-di(methanesulfonyloxy)ethane (III). A column chromatography over silicagel allows the separation of the (E)- and (Z)-isomers.

合成路线2

该中间体在本合成路线中的序号:(IV)

This compound has been obtained by two similar ways: The enantiocontrolled reduction of 2,4-dichlorophenacyl bromide (I) with BH3/THF and a chiral oxazaborole catalyst gives 1(S)-(2,4-dichlorophenyl)-2-bromoethanol (II), which is treated with Ms-Cl and TEA in dichloromethane to yield the corresponding mesylate (III). Finally, this compound is cyclized with 2-(1-imidazolyl)-3,3-disulfanylacrylonitrile (VI) by means of KOH in DMSO. Alternatively, 1(S)-(2,4-dichlorophenyl)ethane-1,2-diol (VII) is treated with Ms-Cl and TEA in dichloromethane to give the corresponding dimesylate (VIII), which is condensed with the acrylonitrile (VI) with KOH as before. The intermediate acrylonitrile (VI) has been obtained by condensation of 2-(1-imidazolyl)acetonitrile (IV) with CS2 (V) by means of KOH in DMSO.
