合成路线2
该中间体在本合成路线中的序号:(I)The reaction of 1,3-dichloro-2-propanol (I) with Bn-ONa gives 1,3-dibenzyloxy-2-propanol (II), which by reaction with paraformaldehyde and HCl is converted into the chloromethyl ether (III). The reaction of (III) with potassium acetate affords the acetoxymethyl ether (IV), which is condensed with diacetylguanine (V) by means of TsOH to provide fully protected ganciclovir (VI). Finally, this compound is debenzylated to (VII) with Pd(OH)2/cyclohexene and deacetylated with ammonia in methanol.
