Functional-group-tolerant, nickel-catalyzed cross-coupling reaction for enantioselective construction of tertiary methyl-bearing stereocenters

The first Negishi nickel-catalyzed stereospecific cross-coupling reaction of secondary benzylic esters is reported. A series of traceless directing groups is evaluated for ability to promote cross-coupling with dimethylzinc. Esters with a chelating thioether derived from commercially available 2-(methylthio)acetic acid are most effective. The products are formed in high yield and with excellent stereospecificity. A variety of functional groups are tolerated in the reaction including alkenes, alkynes, esters, amines, imides, and O-, S-, and N-heterocycles. The utility of this transformation is highlighted in the enantioselective synthesis of a retinoic acid receptor agonist and a fatty acid amide hydrolase inhibitor.

Biphenyl derivatives substituted by an aromatic or heteroaromatic radical and pharamaceutical and cosmetic compositions containing same

“Biphenyl derivatives substituted with an aromatic or heteroaromatic radical, and pharmaceutical and cosmetic compositions containing them” in which: Ar represents an aromatic or a heteroaromatic radical optionally substituted, in particular, with an alkyl or a carboxyl group, R2and R3represent, in particular, H or alkyl, or R2and R3, taken together, form a 5- or 6-membered ring, R4and R5represent, in particular, H or halogen, R6represents, in particular, H or lower alkyl, and the salts of the compounds of formula (I). These compounds can be used in particular in the treatment of dermatological complaints associated with a keratinization disorder, and for combating ageing of the skin.
