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

?cyanoethylthio group is effected by treatment with 2,4,6?triisopropybenzenesulfonyl chloride and triethylamine to give a 6?(2,4,6?triisopropylbenzenesulfonic acid) ester intermediate. Reaction of this key intermediate with 3?mercaptoproprionitrile
