The Synthesis of Bridged Purine Dinucleoside

摘要

Two bridged purine dinucleosides, bis(2-N-acetyl-6-N-alkylylene-2, 6-diaminopurine-2’,3’,5’-triacetyl-β-D-ribofuranoside),were synthesized from the reaction of the key medium 3, 2-acetylamino-6-[1-(1,2,4-triazolyl)]-purine-2’,3’,5 ’-triacetyl-α-D-ribofuranoside with dialkylamine.
