| titleOfInvention | Process for the preparation of alkyl esters of unsaturated alpha-hydroxy carboxylic acids |
| abstract | worin R 1 Wasserstoff, Methyl oder Ethyl, R 2 Wasserstoff oder Alkyl mit 1 bis3 C-Atomen und R' Alkyl mit 1 bis 6 C-Atomen bedeutet, wobei man ein Cyanhydrin der allgemeinen Formeln worin R' und R 2 obige Bedeutung haben (oder eine entsprechende Gleichgewichtsmischung aus einem Alkylalkenylketon der Formel CH 2 = CR 1 -CO-CH 2 -R 2 und Blausäure), in Gegenwart von Chlorwasserstoff mit einem Alkohol der allgemeinen Formeln worin R 3 obige Bedeutung hat, umsetzt und das erhaltene Reaktionsgemisch hienach hydrolysiert. Process for the preparation of partially new unsaturated hydroxy esters of the general formula wherein R 1 is hydrogen, methyl or ethyl, R 2 is hydrogen or alkyl having 1 to 3 C atoms and R 'alkyl having 1 to 6 C atoms, wherein a cyanohydrin of the general formula wherein R 'and R 2 have the above meaning (or a corresponding equilibrium mixture of an alkylalkenyl ketone of the formula CH 2 = CR 1 -CO-CH 2 -R 2 and hydrocyanic acid), in the presence of hydrogen chloride with an alcohol of the general formula wherein R 3 has the above meaning, and the reaction mixture obtained is subsequently hydrolyzed. n n n The compounds obtained in this way are suitable for the preparation of alkaloids and crop protection agents and as monomers for copolymerization. |
