The common bases found in DNA are guanine (G), adenine (A), cytosine (C), and thymine (T), while the common RNA bases are G, A, C and uracil (U). RNA also differs from DNA in that it bears a hydroxy group in the 2′ position. The five-membered furanose ring (ribose or ...

and 8; Supplementary Tables6and7). Various solvents were then screened; the use of mesitylene improved the yield to 94%, but the enantioselectivity decreased slightly (Table1, entry 9 and Supplementary Table8). Mesitylene was used as the solvent in the further screening of the bases and ...

Use of combined bases and mixed solvents would improve the deprotonation of carboxylic acids to expedite the acyl radical generation and use of the precise amount of a ligand would promote the acyl radical oxidative addition to the arylnickel (II) species. We speculated that a facile C–O bond...
