| titleOfInvention | Production of jasmonic ester intermediate |
| abstract | PURPOSE: The reaction between a vinyl ketone and a β-nitropropionic ester gives an α,β-unsaturated carboxylic ester, a synthetic intermediate of jasmonic ester used as a perfume readily in high yield. n CONSTITUTION: The concenetration reaction between a vinyl ketone of formula I (R 1 is alkyl, alkenyl) such as hexyl vinyl ketone, 3-hexenyl vinyl ketone, and a β-nitropropionic ester of formula II (R' is alkyl, aryl) is conducted in the presence of a weak base such as a secondary amine, e.g., dialkylamine, or potassium fluoride in a solvent such as tetrahydrofuran or dimethylformamide at 0W40°C to produce 6-oxo-2-dodecenoic ester or 6-oxo-(2Z, 9E)-2,9-dodecadienoic ester. n COPYRIGHT: (C)1982,JPO&Japio |
