[GRAPHICS]A short synthesis of (+/-)-brazilin is reported. This synthesis uses several interesting and underutilized transformations including a regioselective dirhodium-catalyzed aryl C-H insertion, a regioselective IBX phenol -> o-quinone oxidation, a tautomerization of an o-quinone to a p-quinone methide, and an intramolecular aryl cyclization with a p-quinone methide.

The present invention relates to a cosmetic composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising: a) one or more fatty substances; b) one or more surfactants; c) one or more oxidation bases; d) one or more couplers based on 2-hydroxynaphthalene derivatives or particular phenol derivatives, acylaminophenol derivatives or quinoline derivatives; f) one or more basifying agents; e) optionally one or more chemical oxidizing agents; and the fatty substance content representing in total at least 25% by weight relative to the total weight of the formulation. The present invention also relates to a process using this composition, and to a multi-compartment device that is suitable for performing the said process.
