nonsteroidal estrogens. In contrast to the diphenyldihydronaphthalenes, the diarylindene and -indenone systems undergo photocyclization to phenanthrenes inefficiently. The estrogenreceptor binding affinity of these systems is reasonably high (9-59% relative to estradiol), with the indenone systems having higher affinity than the indenes; additional hydroxyl substitution raises the affinity of the indenes

A novel controlled DTBP-mediated oxidative C–S bond cleavage/annulation cascade is devised. This approach enables the controlled formation of carbonyl intermediates frombenzyl thioethers to participate in annulation reactions with alkynes to offer privileged indenone skeletons.

represents one of the first examples of the addition of an organopalladium moiety to the carbon-nitrogentriplebond of a nitrile. The reaction is compatible with a number of functional groups. A reaction mechanism, as well as a model accounting for the electronic effects of substituents on the aromatic ring of the nitrile, is proposed.
