An optimized approach for the synthesis of N1-ethoxymethyl-substituted cyclic inosine diphosphoribose (cIDPRE), an analogue of cyclic adenosine diphosphoribose (cADPR), has been developed via microwave-assisted intramolecular cyclization. The target compound has been successfully obtained through N1-substitution, phosphorylation, cyclization and deprotection. By using this method, 8-amino and bromo-substituted cIDPRE analogues were successfully obtained in good yield. The new approach has greatly shortened the synthetic route and enhanced the overall efficiency.

Key words: cADPR, cIDPRE, Chemical synthesis, Microwave-assisted synthesis
