  To fold or not to fold? It is shown that attached sugars play a defining role in the conformations adopted by a pair of novel SAA‐derived foldamers in water and that these differences are reflected in the contrasting interactions of these glycofoldamers with various biological targets.

  The selection of artificial nucleic acids to be used for synthetic biology purposes is based on their structural and biochemical orthogonality to the natural system. We describe the example of a nucleotide mimic that functions as a substrate for polymerases and in which the carbohydrate moiety as well as the base moiety and the leaving group are different from that of the natural building blocks. The nucleotides themselves have two anomeric centers, and different leaving group properties of substituents at both anomeric centers need to be exploited to perform selective glycosylation reactions for their synthesis. In addition, the reversibility of the polymerase reaction at the level of the template has been demonstrated when pyrophosphate functions as leaving group and not with the alternative leaving groups.
• Synthesis of 2‘,5‘-Dideoxy-2-fluoroadenosine and 2‘,5‘-Dideoxy-2,5‘-difluoroadenosine:  Potent P-Site Inhibitors of Adenylyl Cyclase

  Glycosylation of 2-fluoroadenine with the appropriate protected thioglycoside derivatives, followed by deprotection and anomer separation, produced the alpha- and beta-anomers of 2',5'-dideoxy-2-fluoroadenosine (1), 2',5'-dideoxy-2,5'-difluoroadenosine (2), and 2'-deoxy-2-fluoroadenosine (3). These were examined as P-site inhibitors of adenylyl cyclase. The presence of fluorine on the purine ring increased potency of inhibition, and the most potent compound, beta-2',5'-dideoxy-2-fluoroadenosine (1b), was 3 times more potent than beta-2',5'-dideoxyadenosine.
