Abstract
NEW MATERIAL:An acetonedicarboxylic ester of formula I (R is ≤6C alkyl).
EXAMPLE: Dimethyl 2-(2'-propynyl)-3-oxoglutarate.
USE: An intermediate for agricultural chemicals, an intermediate for cyclopentenolone of formula III necessary for the production of an ester of formula II having highly powerful knockdown and lethan effects.
PROCESS: An acetonedicarboxylic acid ester of formula IV is reacted with a halogenide of formula V (X is halogen), in the presence of a base, to obtain a compound of formula I.
