Sažetak
Succinimide-functionalized N, O-, N, C-, and N, N-bridged benzo[ 2] polynorbornanes ( benzosesquinorbornadienes) are reported for the first time and are prepared by the cycloaddition of either five-membered cyclic 1, 3-dienes onto N-substituted benzo-7-azanorbornadienomaleimides or N-substituted isoindoles onto the appropriate norbornadienomaleimides. These products contain an end-fused norbornene ( or a 7-substituted relative) and have been designed to act as alkene BLOCKs for the production of nano-scaffolds with up to six addressable sites supplied by each norbornene unit. The N-bridges in these BLOCKs ( and their coupled products) allow N-substituent mobility by invertomerization of the sp(3) nitrogen whereas the N-substituents on the succinimides are attached to an sp(2) nitrogen atom and remain static. Preferred invertomer geometry can be determined using molecular modelling.
