Synthesis of C8-alkyl-substituted purine analogues by direct alkylation of 8-H purines with tetrahydrofuran catalyzed by CoCl2·6H2O
2017
Abstract C8-Alkyl-substituted purine analogues were synthesized through direct alkylation of 8- H purine with tetrahydrofuran in the presence of Co catalyst in one step. The reactions gave a series of novel C8-oxygen heterocyclic alkyl purine compounds in good yields under mild reaction conditions by the readily available alkylating reagents, providing a complementary route to the classical coupling reactions for the synthesis of C8-alkyl-substituted purine analogues.
