| description | NOUVEAUX AMINOPHOSPHINE-PHOSPHINITES. LEUR PROCEDE DE FABRICATION ET LEUR APPLICATION A DES REACTIONS ENANTIOSELECTIVES L'invention porte sur des ligands phosphorés chiraux des formules : (II) (III) R et R' dans (II), différents l'un de l'autre, sont des radicaux hydrocarbonés (alkyle, cycloalkyle, aryle, aralkyle ou alkaryle) ; R dans (III) est un radical hydrocarboné (alkyle, cycloalkyle ou aryle) ; R2 = H ou radical hydrocarboné, éventuellement porteur d'une fonction CO dans (II), et porteur d'une fonction CO dans (III) ; R3, R4, nécessairement différents sauf si R5 et R6 sont différents, = H, radical hydrocarboné éventuellement fonctionnalisé ; R5 et R6 , H ou radical hydrocarboné éventuellement fonctionnalisé; l'un parmi R3 et R4 pouvant porter une fonction -OPR2 ou -NPR'2 -NPR2) ; R2 et R3 et les N et C qui les portent respectivement pouvant former ensemble un hétérocycle ; ou bien R2 et R5, les N et C qui les portent respectivement et le C intermédiaire pouvant former ensemble un hétérocycle. Application à une réaction énantiosélective (hydrogénation de composés carbonylés par exemple).
Chiral phosphorus-containing ligands of the formulae: R and R' in (II), which differ from each other, are hydrocarbon (alkyl, cycloalkyl, aryl, aralkyl or alkaryl) radicals; R in (III) is a hydrocarbon (alkyl, cycloalkyl or aryl) radical; R = H or hydrocarbon radical, optionally carrying a CO functional group in (II) and carrying a CO functional group in (III); R and R , necessarily different except when R and R are different, = H, optionally functionalised hydrocarbon radical; R and R = H or optionally functionalised hydrocarbon radical; it being possible for either of R and R to carry an -OPR2 or -NPR'2-NPR2) functional group; it being possible for R and R and the N and C which carry them respectively to form a heterocyclic ring together; or else it being possible for R and R , the N and C which carry them respectively and the intermediate C to form a heterocyclic ring together. Application to an enantioselective reaction (for example, hydrogenation of carbonyl compounds). |
