| titleOfInvention | Procedure for the preparation of tetrahydropyranylesters |
| abstract | Process for the preparation of tetrahydropyranylesters of the general formula (I) ** (See formula) ** in which R1, R2, R3 and R4 independently represent hydrogen, C1-C12 straight or branched chain alkyl, C2 alkenyl -C12 straight or branched chain, cycloalkyl unsubstituted or substituted with C1-C12 alkyl and / or C1-C12 alkoxy with a total of 3 to 20 carbon atoms, or aryl unsubstituted or substituted with C1-C12 alkyl and / or alkoxy C1-C12 with a total of 6 to 20 carbon atoms, R5 represents hydrogen or C1-C12 straight or branched chain alkyl, and Ra and Rb represent hydrogen, in which at least one 4-hydroxy-tetrahydropyran compound is prepared from the general formula (II) ** (See formula) ** in which R1, R2, R3, R4 and R5 have the meanings indicated above and the compound of the general formula (II) supports a reaction with a ketene (III) CRaRb = C = O (III) in which Ra and Rb have the meanings indicated above. |
