    摘要: Disclosed are coumarin derived compounds of formula I as skin lightening agents alone or in combination with other skin benefit agents and together with a cosmetic vehicle: Where each or both R1 and/or R2 represents hydrogen (H); linear or branched, saturated or unsaturated C1-C12 alkyl, alkenyl, acyl, or heteroalkyl (preferably, alkoxy) groups; and R3 represents linear or branched, cyclic or acyclic, saturated or unsaturated C1-C12 alkyl, alkenyl, cycloalkyl, cycloalkenyl, or heteroalkyl group; and R4 represents a hydrogen atom (H); straight or branched, cyclic or acyclic, saturated or unsaturated, containing or not containing a heteroatom C1-C22 alkyl, alkenyl, cycloalkyl, cycloalkenyl, heteroalkyl, aryl, or heteroaryl group. In a most preferred embodiment, each R1, R2 and R4 represent H, while R3 represents a methyl group, referred to herein as a 4-methyl 7-hydroxy-coumarin derivative, or coumarin derived resorcinol derivative, which may be prepared by catalytic (nickel or paladium catalyst) hydrogenation of 4-methyl 7-hydroxy-coumarin followed by hydrolysis. The inventive compounds, compositions and methods have effective skin lightening properties, may be less irritating to the skin, and are cost-effective and relatively simple to manufacture. Also disclosed are processes for making the inventive compounds of general formula I from 4-substituted-7-hydroxy coumarin derivatives.

    摘要: Process for carboxy-alkylation, particularly carboxymethylation, of branched alcohols includes the reaction of isoalcohols with potassium-t-butoxide or sodium-t-butoxide and with salt of halogenated alkanoic acid in the presence of the isoalcohol (starting alcohol) as the solvent. Produced are isoalcohol carboxy-alkylates (preferably, carboxymethylates) in excellent yields and purity.
