Method of preparing a 3-alkoxy-2-alkyl-propionic acid ester derivative and intermediate therefor |
| abstract |
3-Alkoxy-2-alkyl-propionic acid derivatives are prepared by catalytic hydrogenation of the acrylic acid analogs. The latter are obtained by CO treatment of lower alkyl esters of alkanoic acids having 3-6 carbon atoms in the presence of alkali metal methylate and condensation of the resulting 2-formylalkanoic acids or their alkali metal enolates with compounds of the formula X--(CH 2 ) m --Z wherein X is Cl, Br, or OH, and Z is Cl, Br, I, alkyl- or arylsulfonyl, or OH. |
