| titleOfInvention | (S)- or (R)-epsilon-(2-alkyloxyethyl)-epsilon-caprolactone, preparation method and application thereof |
| abstract | The invention discloses novel compound (S)-or(R)-Epsilon-(2-alcoxyl ethide)-Epsilon-caprolactone showed in the formula 1 and the preparation method thereof, and an application in synthesizing (S) or (R)-6-hydroxide radical-8-alkoxyl octanoic acid or ester thereof used as important reaction intermediate. In the formula 1, R1 is the alkyl of C1-C4 or phenethyl-C2H4Ph. The invention has the advantages of simple steps, mild condition, effectively transforming racemization 2-(2-alcoxyl ethide) cyclohexanone into (S) or (R)-2-(2-alcoxyl ethide) cyclohexanone which has the relatively high optical purity, and finally Baeyer-Villiger oxidizing (S) or (R)-2-(2-alcoxyl ethide) cyclohexanone to produce the compound showed in the formula 1, with the same shape of the product. The application of the compound of the invention used as the reaction intermediate can simplify the preparation method for (S) or (R)-6-hydroxide radical-8-alkoxyl octanoic acid and the ester thereof, thereby being suitable to the industrial production. |
