A novel strategy has been devised for the synthesis of pyrrole based acyclo-C-nucleosides, in particular an open-chain sugar substituted pyrrole derivatives by means of the condensation of 2-C-formyl glycals with α-amino acids through an intramolecular azomethine cycloaddition under thermal conditions. The use of cyclic α-amino acids provides the corresponding bicyclic pyrrole derivatives. This is a first report on the synthesis of pyrrole based acyclo-C-nucleosides. 2009 Elsevier Ltd.

A convenient protocol was developed for the synthesis of 2,3-unsaturated C-, O-, N- and S-linked glycosides (enosides) using 20 mol % perflurophenylboronic acid catalyst via Ferrier rearrangement. Using this protocol, D-glucals and L-rhamnals reacted with various C-, O-, N- and S-nucleophiles to give a wide range of glycosides in up to 98% yields with mainly α-anomeric selectivity. The perflurophenylboronic acid successfully catalyzed a wide range of substrates (both glucals and nucleophiles) under very mild reaction conditions.

A highly efficient method to afford 2,3-unsaturated glycosides was described. In the presence of Hafnium(IV) triflate, a variety of 2,3-unsaturated-O- and S-glycosides have been obtained by stereoselective glycosylation of 3,4,6-tri-O-acetyl-d-glucal and hexa-O-acetyl-d-lactal with various acceptors in good isolated yields.
