RESUMO
The synthesis of novel indolizine C-nucleoside analogues has been achieved by the three-component coupling reaction of sugar alkynes, pyridines and α-bromo carbonyl compounds in one pot. The corresponding products are obtained in good to excellent yields. 49 examples have been given. The synthetic method is convenient, practical and efficient. It is suitable for various substrates including structurally diversified sugar alkynes with sensitive groups. The sugar alkynes include pyranosides, furanosides, and acyclic sugars. A plausible mechanism for the formation of indolizine C-nucleoside analogues has been elucidated.
