  • CATALYTIC SYNTHESIS OF ANTI-UV AND ANTIOXIDANT CONJUGATED 8-8 DIMERS IN A GREEN SOLVENT
    Publication number: 20220009874
    Abstract: A process for preparing b-b dimers having anti-UV and antioxidant properties, from p-hydroxycinnamic esters and amides disubstituted in the ortho position with respect to the phenol function and from ketones disubstituted in the ortho position with respect to the phenol, in particular, from sinapic acid esters and amides and ketone analogs. The dimers of formulae (I), (II), (III) and (IV) as obtained by means of the process according to the present disclosure can be used for the production of polymers/plastics (in plastics technology), or for the protection of plants against the cold and as cosmetic or food-processing ingredients, for example. The process may be used to form biobased anti-UV molecules.

  • METHOD FOR CONVERTING LEVOGLUCOSENONE INTO 4-HYDROXYMETHYL BUTYROLACTONE AND 4-HYDROXYMETHYL BUTENOLIDE WITHOUT USING ANY ORGANIC SOLVENT AND CATALYST
    Publication number: 20190210990
    Abstract: The invention relates to a method for converting levoglucosenone into 4-hydroxymethyl butyrolactone and 4-hydroxymethyl butenolide without using any solvent or catalyst, wherein the oxidation and hydrolysis of the levoglucosenone or hydrogenated levoglucosenone are carried out in a single step using an aqueous solution of H2O2.

  • METHOD FOR TRANSFORMING LEVOGLUCOSENONE INTO 4-HYDROXYMETHYN BUTYROLACTONE OR 4-HYDROXYMETHYL BUTENOLIDE
    Publication number: 20170152536
    Abstract: The disclosure relates to a method for transforming levoglucosenone into 4-hydroxymethyl butyrolactone or 4-hydroxymethyl butenolide, comprising a step involving the oxidation of the levoglucosenone, or dihydrolevoglucosenone obtained by hydrogenation of levoglucosenone, by bringing a solution of levoglucosenone or dihydrolevoglucosenone in a solvent into contact with a lipase in the presence of an oxidizing agent and an acyl donor compound. The oxidation step is followed by a step involving the hydrolysis of the reaction mixture obtained and, if necessary, a step involving the hydrogenation of the compound obtained at the end of the hydrolysis step.
