Novel 3',5'-cyclic nucleotide analogue: adenosine 3',5'-cyclic boranomonophosphate.
A general procedure for the first synthesis of a 3',5'-cyclic boranomonophosphate was established. Specifically, adenosine 3',5'-cyclic boranomonophosphosphate (cyclic AMPB, 4c), a P-borane (BH(3)) analogue of adenosine 3',5'-cyclic monophosphate (cAMP), was synthesized via a phosphite approach in good yield. The method is also applicable for syntheses of natural cAMP and its phosphorothioate analogue. The two diasteromers of cyclic AMPB 4c were separated, and their chemical structures were established via spectroscopic methods.
