| titleOfInvention | Preparation method 1- (3-cyclopentenyloxy-4-alkoxyphenyl) -4-oxo-cyclohexanecarbonitrile |
| abstract | A new process for the preparation of 1- (3-cyclopentyloxy-4-alkoxyphenyl) -4-nof the oxocyclohexanecarbonitrile of formula (I) in whichndialkyl ester of dibasic 4-cyano-4- (3-cyclopentyloxy-4-nthe methoxyphenyl) heptane of formula (P) is cyclized tonthe presence of a base to give the 5-cyano-5-alkyl alkyl estern(3-cyclopentyloxy-4-alkoxyphenyl) -2-nthe oxocyclohexanecarboxylic acid of formula III, thennthe compound of formula III is neutralizednalkali metal bicarbonate, and finallyndecarboxylate in the presence of an alkali metal carbonate tonthe final product of formula I was obtained. |
