Abstract

Additional examples in the biphenyl series of the condensation of a nitro group in the 2- position with an activated methylene group in the Z'-position in the presence of methanolic sodium hydroxide have been found. The additional act, ivating groups are benzoyl and benzenesulfonyl; the phenyl group did not serve as an activator. Apparently, the benzoyl and benzenesulfonyl compounds underwent ring closure followed by nucleophilic ...
