Benzoyl cyanide in the ionic liquid 1-methoxyethyl-3-methylimidazolium methanesulfonate has been employed as a 'green' alternative and mild reaction condition protocol to conventional pyridine-benzoyl chloride system for efficient and selective benzoylation of nucleosides (of both the ribo- and deoxyribo-series) at ambient temperatures. The use of benzoyl cyanide-ionic liquid combination has been successfully extended for highly efficient benzoylation of phenols, aromatic amines, benzyl alcohol, aliphatic diols, 3-aminophenol and 2-aminobenzylalcohol, which indicates the versatility of this benzoylating system.

Use of benzoyl cyanide (BzCN) for benzoylation of nucleosides has been studied, both in pyridine and in ionic liquid. BzCN in 1-methoxyethyl-3- methylimidazolium methanesulfonate as ionic liquid has been found to be a "green" alternative compared to the pyridine-BzCN system. An efficient and selective benzoylation of nucleosides of both, the 2′-deoxy- and the ribo-series at ambient temperature was accomplished. Copyright Taylor & Francis, Inc.

The several steps of the Friedel-Crafts catalyzed silyl-Hilbert-Johnson nucleoside synthesis - silylation of the heterocyclic base, silylation of the perfluorosulfonic acids or its salts (if SnCl4 is not used as catalyst) and finally the nucleoside synthesis itself - can be combined to a simple one-step/one-pot reaction which generally affords nucleosides in high yields.
