Fused benzo[b]fluorenols: Palladium-catalyzed intramolecular dehydroaromatization and carbonyl reduction

Benzo[b]fluorenols were prepared by a new palladium-catalyzed one-pot reaction of en-one-ynes with 3-bromoprop-1-yne through intramolecular dehydroaromatization and carbonyl reduction. Copyright

Copper-catalyzed intramolecular oxidative 6-exo-trig cyclization of 1,6-enynes with H2O and O2

The novel CuCl2-catalyzed title reaction of enynes has been developed for synthesizing substituted naphthoquinones (see scheme; DMA=dimethylacetamide). The method represents the first example of a copper-catalyzed enyne oxidative cyclization for constructing 1,4-naphthoquinones by the incorporation of two oxygen atoms into the organic framework from molecular oxygen and water.
