Facile Synthesis of O6-Alkyl-, O6-Aryl-, and Diaminopurine Nucleosides from 2‘-Deoxyguanosine
摘要:
[GRAPHICS]The 3',5'-bis-O-TBDMS derivative of 2'-deoxyguanosine can be converted to its O-6-alkyl and O-6-aryl ethers as well as to N-6-substituted diaminopurine nucleosides in two simple steps. Also described is a novel, nonaqueous, one-step O-6-desulfonylation method that leads to deprotection of the carbonyl moiety of 2'-deoxyguanosine.
