Preparation of cyclic AMP derivatives by intramolecular phosphodiester bond formation catalyzed by Pb2+ ion.
摘要:
Cyclic AMP derivatives containing a carbocyclic sugar moiety were prepared by lead-ion catalyzed intramolecular phosphodiester-bond formation of carbocyclic nucleoside-5'-phosphorimidazolide in aqueous solution. The catalytic effect of other metal ions and the properties of the cyclic AMP derivatives are described.
