Abstract


Reactions of chiral nopinane-annulated diazafluorenone with substituted phenols and naphthols by the action of trifluoromethanesulfonic acid led to spiro products. The structure of the resorcinol derivative was confirmed by X-ray structural analysis.


Keywords


chiral bipyridyls; chiral pyridines; diazafluorenes; spiro compounds; terpenes; chirality; donor-acceptor systems; electrophilic alkylation.
