5-Norbornene-2,3-dicarboximido Carbonochloridate. A New Stable Reagent for the Introduction of Amino-Protecting Groups
The synthesis of activated carbonates, based on a new carbonochloridate derived from N-hydroxy-5-norbornene-2,3-dicarboximide, is reported.These activated carbonic esters are excellent reagents for the introduction of all currently used urethane protecting groups.
