The thermal rearrangement of [3]polynorbornane bis-imide rack-mounted 7-oxabenzonorbornadienes has been conducted using flash vacuum pyrolysis (FVP) at 520°C and is compared with the FVP of similar 7-oxabenzonorbornadienes off the rack. The isomerisation is considered to involve (a) C...

oxabenzonorbornadieneA tandem isomerization/hydroarylation reaction of oxabenzonorbornadienes and arylacetylenes was realized by using AgOTf as catalyst. 1,1-Diarylethylenes could be easily generated as products in moderate to good yields in this tandem reaction.Yongyun...
The first aminomethylation of oxabenzonorbornadienes using dual photoredox/nickel catalysis has been disclosed. This cascade reaction allowed the preparation of the cis-aminomethyl dihydronaphthalenols without any prefunctionalization or any use of nucleophilic organometallic species. The control of the ...

rutheniumRuthenium-catalyzed nucleophilic ring-opening reaction of 7-oxabenzonorbornadienes with methanol was investigated. Among various ruthenium catalysts tested, Cp* Ru (COD)Cl gave the greatest yields in the ring-opening reaction. The reactions were found to be highly stereoselective, giving ...
