novel approach to the synthesis of purine derivatives (bases and nucleosides) bearing 4,5-dihydrofuran-2-yl and tetrahydrofuran-2-yl substituents at the 6-position as partly and fully saturated analogues of biologically active 6-hetarylpurine nucleosides is reported. Palladium-catalyzed cross-coupling reactions of 6-iodopurines with new (4,5-dihydrofuran-2-yl)zinc chloride (1) gave 6-(4,5-dihydrofuran-2-yl)purines
