Synthesis of non-symmetrical 3,5-diamidobenzyl amines, ethers and sulfides

A straightforward synthesis of non-symmetrical 3,5-diamidobenzyl amines, ethers and sulfides starting from 3,5-dinitrobenzoic acid is reported. Functionalization of the benzylic position is only achieved after formation of the two amides, otherwise benzylic hydrogenolysis occurs during nitro group reduction.

Methods for dyeing keratinous fibres with aminoindoles, compositions and devices for use

Method for dyeing keratinous fibres, in particular human keratinous fibres, such as hair, characterized in that a composition (A) containing, in a medium appropriate for dyeing, at least one aminoindole corresponding to the formula: STR1 in which: R1 and R3, independently of one another, represent a hydrogen atom or a C1 -C4 alkyl group; R2 denotes hydrogen or a C1 -C4 alkyl group or COOR', R' being a hydrogen atom or a C1 -C4 alkyl group; R4 represents a hydrogen atom or a C1 -C4 alkyl, C1 -C4 hydroxyalkyl or C2 -C4 polyhydroxyalkyl group; Z1 represents a hydrogen or halogen atom or a C1 -C4 alkyl group or OR; R being a hydrogen atom or a C1 -C4 alkyl group; and Z2 represents a hydrogen atom or a C1 -C4 alkyl group; and its salts is applied to said fibres, the colour being developed with the aid of an oxidizing system.
