Bicyclic ether scaffolds are found in a variety of natural products and are of interest in probe and drug discovery. A palladium-catalyzed cascade reaction has been developed to provide efficient access to these scaffolds from readily available linear diene-diol substrates. A Pd redox-relay process is used strategically to transmit reactivity between an initial oxypalladative cyclization and a subsequent π-allyl-Pd cyclization at remote sites. The reaction affords a variety of bicyclic ether scaffolds with complete diastereoselectivity for cis-ring fusion.

The invention relates to an oxidative coloring agent for keratin fibers, in particular hair based on a developing agent-coupling agent combination, which contains as a developing agent at least one 2-hydroxy-5-amino-biphenyl derivative of general formula (I) in addition to novel 2-hydroxy-5-amino-biphenyl derivatives.
