| titleOfInvention | 2-oxocyclopentanecarboxylic acid derivative and its preparation |
| abstract | NEW MATERIAL:The compound of formula I (R 1 , R 2 and R 3 are H or lower alkyl; R 4 is lower alkyl; the dotted line is double or triple bond; when the line is double bond, Z is H). n EXAMPLE: 1-(2-Pentynyl)-2-oxocyclopentanecarboxylic acid allyl ester. n USE: Intermediate of perfumery substance such as methyl jasmonate, cis-jasmone, etc. n PREPARATION: The compound of formula I can be produced by reacting 1mol of the enol salt of 2-oxocyclopentanecarboxylic acid ester of formula II with 0.5W3mol, preferably 0.7W1.5mol of the halogenated unsaturated hydrocarbon of formula III at 0W200°C, preferably 50W150°C in an inert solvent (e.g. acetone, methyl ethyl ketone etc.). If necessary, the yield can be improved by adding a quaternary ammonium salt or quaternary phosphonium salt to the reaction system. n COPYRIGHT: (C)1985,JPO&Japio |
