The present invention relates to methods and intermediates for the synthesis of nucleosides and nucleoside analogues (NAs). More specifically, the present invention relates to methods of synthesizing nucleosides and NAs, using simple achiral materials by a 'one-pot' proline-catalyzed halogenation of a heteroaryl-substituted acetaldehyde together with a tandem enantioselective aldol reaction followed by a reduction or organometallic addition and cyclization (annulation) reaction involving halide displacement.
Novel mimetics of CMP-sialic acid were designed as the inhibitors of sialyltransferases. They were synthesized in a short step from a cytosine carrying β-hydroxy-α-l-amino acid based on the knowledge that nikkomycin, a peptidic derivative of an uracil carrying amino acid, shows a potent inhibitory activity toward N-acetyl-d-glucosaminyltransferases that employ UDP-N-acetyl-d-glucosamine as the donor substrate. The cytosine carrying β-hydroxyl-α-l-amino acid, a key intermediate in our synthetic strategy, was easily prepared by the l-threonine aldolase (LTA) catalyzed reaction.

efficient one-pot three-component Kabachnik–Fields reaction of aldehydes (acyclicnucleosides), amines (or amino acid), and triethyl phosphite proceeded for the synthesis of aminophosphonates using natural phosphate coated with iodine (I2@NP) as a catalyst. The novel α-aminophosphonate and phosphonicacidacyclicnucleosides were tested for their anti-HCV and anti-HIV activities. The molecular docking
