A highly efficient and general solid-phase synthesis of bicyclic pyrimidine derivatives that target purine dependent proteins is reported. The synthesis of the key intermediate, 4,6-disubstituted-5-amino-pyrimidine, involved reduction of the corresponding nitro derivatives using 1,1'-dioctyl-viologen in a triphasic milieu. The mild reduction conditions enable the use of any acid labile solid support
A novel synthetic method of 8-oxoadenine derivatives (3 and 4) is reported. This widely applicable synthetic method was realized through the use of 5-aminlo-4-cyano-2-oxoimidazole derivatives (2) as the key intermediates. A variety of substituents were successfully introduced to the 2- and 9-position of the 8-oxoadenine nucleus.
