Abstract:
A chiral compound obtained by reaction of at least one hydrogen of an alcohol, amine, or thiol function of at least one chiral unit of a product with at least one group Q of a bifunctional alkenoxyaryl or alkenylaryloxyaryl type compound with formula (Râ€”CH&boxH;CHâ€”(X)â€”O)nâ€”Arâ€”Q,where Q is â€”N&boxH;C&boxH;O or a precursor thereof; â€”NH2or â€”CON3; â€”COCl or its precursor; â€”COOH; â€”N&boxH;C&boxH;S; or â€”CH2Y, where Y is Cl or Br or I or methylsulphonyloxy or paratoluenesulphonyloxy or 3,5-dimethylphenylsulphonyloxy and where: n is in the range 1 to 20; R is hydrogen or a linear or branched alkyl group or a linear or branched alkoxy group or hydroxyl or an aryl group, optionally substituted; X is a linear alkyl group carrying more than one carbon atom or a branched alkyl group, or an aryl group, optionally substituted with at least one group selected from the group consisting of hydrogen, alkyl, alkoxy, hydroxyl and trihalogenoalkyl groups; and Ar is an aryl or polyaryl group, optionally substituted with at least one hydrogen atom or with at least one group selected from the group consisting of alkyl, alkoxy, hydroxyl, trihalogenoalkyl, silyl, thiol, amino, aminoalkyl, amide, nitro, nitrosamino, N-amino, aldehyde, acid and ester groups, excluding the following compounds: 4-allyloxyaniline, 4-allyloxybenzoic acid, its acid chloride, and 4-allyloxyphenylisocyanate.
