The present invention relates to a selective reduction of esters to their corresponding alcohols.

Selective reduction of esters to alcohols

The invention relates to a process for the production of 5-formylvaleric acid and adipic acid or esters thereof from an isomeric mixture of pentenoic acid or esters thereof said mixture comprising at least 4-pentenoic acid or esters thereof, and further comprising 3-pentenoic acid and/or 2-pentenoic acid or esters thereof. The process allows for efficient production of two different intermediates for producing polyamide using a single process, with good selectivity, little waste, in an economically efficient fashion. The process is very suitable to use an isomeric pentenoic acid mixture obtained from valerolactone, and can be used to produce renewable polyamide intermediates using a single process.

Process for the preparation of formylvaleric acid and adipic acid

A process for producing furfural and levulinic acid from lignocellulose-comprising biomass is disclosed. The biomass is slurried using water and optionally an acid, subjected to hydrolysis, and then subjected to a solid/liquid separation to yield at least an aqueous fraction comprising C5 and C6 sugars and a solid fraction comprising cellulose and lignin. Furfural is obtained by adding an organic solvent to the aqueous fraction, heating at 120-220&#xb0; C. for a sufficient time to form furfural, cooling, and separating an organic phase comprising at least part of the furfural from an aqueous phase. Levulinic acid is obtained by suspending the solid fraction in water and optionally an acid, heating the suspension to 140-220&#xb0; C., and separating an aqueous fraction comprising the levulinic acid from a solid fraction.

The present invention relates to a method for preparing caprolactone, comprising converting 5-hydroxymethyl-2-furfuraldehyde by hydrogenation into at least one intermediate compound selected from the group of 2,5-tetrahydrofuran-dimethanol, 1,6-hexanediol and 1,2,6-hexanetriol, and preparing caprolactone from said intermediate compound. Further, the invention relates to a method for preparing 1,2,6-hexanetriol comprising preparing 5-hydroxymethyl-2-furfaldehyde from a renewable source, converting 5-hydroxymethyl-2-furfaldehyde into 2,5-tetrahydrofuran-dimethanol and converting 2,5-tetrahydrofuran-dimethanol into 1,2,6-hexanetriol. Further, the invention relates to a method for preparing 1,6-hexanediol from 1,2,6-hexanetriol, wherein 1,2,6-hexanetriol is subjected to a ring closure reaction, thereby forming (tetrahydro-2H-pyran-2-yl)methanol, and the (tetrahydro-2H-pyran-2-yl)methanol is hydrogenated, thereby forming 1,6-hexane diol.

The invention relates to a process for the isomerization of unsaturated fatty acids or esters or amides thereof, said process comprising reacting: The process is particularly advantageous for the isomerization of substituted alkenes harboring a hydroxy group when the desired end product has a keto group, such as ricinoleic acid or ester thereof.

Process for the isomerisation of substituted alkenes

Described is a method for the preparation of renin inhibitors such as aliskiren, and intermediates useful therein. The method introduces a nitrogen-containing intermediate such as a lactone of formula (8). with Rbeing a branched Calkyl. In the preparation of the lactone, or related intermediates, a desired stereochemical configuration can be controlled by starting from a chiral aldehyde satisfying formula (10). 

Convergent synthesis of renin inhibitors and intermediates useful therein

The present invention relates to a process for the preparation of an enantiomerically enriched optionally substituted indoline-2-carboxylic acid or a salt thereof, wherein an enantiomerically enriched chiral ortho-X-substituted phenylalanine compound, wherein X is a leaving group, is subjected to cyclisation, preferably at a temperature of below about 140&#xb0; C., upon formation of the enantiomerically enriched indoline-2-carboxylic acid compound.
