Synthese de phosphinites derives de sucres: applications en cyclodimerisation du penta 2,4-dienoate de methyle, en hydrogenation et en hydrosilylation de la pentolactone

Sugar-derived phosphinites, when used as ligands in the catalytic hydrogenation of α-ketopentolactone, lead to the corresponding alcohol with a better enantiomeric excess (20percent) than in hydrosilylation (10percent).In the cyclodimerisation of penta-2,4-dienoic acid methyl ester they lead to the meso cycloocta-3,7-diene-1,2-doic dimethyl ester.
