Two‐Step, One‐Pot Synthesis of Inosine, Guanosine, and 2′‐Deoxyguanosine O6‐Ethers via Intermediate O6‐(Benzotriazol‐1‐yl) Derivatives

for the etherification at the O 6 ?position of silyl?protected inosine, guanosine, and 2??deoxyguanosine is described. Typically, a THF solution of the silylated nucleoside is treated with 1H ?benzotriazol?1?yloxy?tris(dimethylamino)phosphonium hexafluorophosphate (BOP

Biotinylation of a Propargylated Cyclic (3′‐5′) Diguanylic Acid and of Its Mono‐6‐Thioated Analog Under “Click” Conditions

%. Phosphitylation of this dinucleoside phosphate triester with 2?cyanoethyl tetraisopropylphosphordiamidite and 1H ?tetrazole, followed by an in situ intramolecular cyclization, gives the propargylated cyclic dinucleoside phosphate triester, which is isolated
