Synthesis of Functionalized Benzo[g]indoles and 1-Naphthols via Carbon-Carbon Triple Bond Breaking/Rearranging

Novel carbon-carbon triple bond breaking and rearranging reactions of benzene-linked allene-ynes have been established. The reactions can be selectively controlled toward the formation of two families of skeletally diverse benzo[g]indoles and 1-naphthols

Synthesis of Functionalized Cyclobutane-Fused Naphthalene Derivatives via Cascade Reactions of Allenynes with tert-Butyl Nitrite

A novel synthesis of cyclobutanol-fused 2-nitronaphthalen-1-ols and nitrocyclobutane-fused naphthalene-1,2-diones through cascade reactions of benzene-linked allenynes with tert-butyl nitrite is presented. The formation of the title compounds involves a tandem process including allenyne [2+2] cycloaddition, radical addition onto the in situ formed cyclobutenyl moiety followed by radical coupling/oxidation. Interestingly, different kinds of functionalized naphthalene derivatives could be obtained selectively from the same substrates, and the selectivity was easily controlled by finely tuning the reaction conditions. (Figure presented.).

Novel platinum-catalyzed tandem reaction: An efficient approach to construct naphtho[l,2-b]furan

An efficient approach to synthesize naphtho[1,2-b]furan has been developed via platinum-catalyzed tandem reaction. This new tandem catalysis induces a cycloisomerization of allenyl ketone, followed by a 6Π-electrocyclization- type reaction of carbene intermediate. The metal carbene proved to be an effective intermediate in the 6π-electrocyclization-type reaction.
