Synthesis of Bicyclic Furo[2,3-d]pyrimidine Deoxynucleosides Conjugated with N-Diisopropylphosphoryl Amino Acids

Article Preview

Abstract:

A series of bicyclic furo[2,3-d]pyrimidine nucleosides conjugated with N-diisopropylphosphoryl amino acids were synthesized from 2′-deoxy-5-iodouridine. The key step is its cross coupling with the 5-phthalimido-1-pentyne under Sonogashira reaction condition. 5-Endo-dig electrophilic cyclization catalyzed by AgNO3 is used to afford the furo[2,3-d]pyrimidines.
