Unexpected reactivity of N2-benzylidene guanosine derivatives
摘要:
Guanosine derivatives masked at the sugar are protected at N-2 by a benzylideneamine group for the first time. The free 5'-hydroxyl function reveals to be incompatible with the N-2-protective group that is then rapidly hydrolyzed to regenerate the free exocyclic amine.
