The invention discloses a
procymidone hapten and a synthetic method and application thereof. The synthetic method comprises the following steps: (1) alpha-chloromethyl
acrylate and methyl methacrylateare used as starting materials to synthesize 1,2-dimethyl-1,2-
cyclopropane dicarboxylic methyl ester; 1,2-dimethyl-1,2-
cyclopropane dicarboxylic methyl ester undergoes
hydrolysis and intramolecular condensation to generate 1,2-dimethylcyclopropane-1,2-
dicarboxylic acid anhydride; (2) 3-chloro-5-
nitrophenol and a compound 3 are used as raw materials to synthesize an intermediate with an arm, and the intermediate is subjected to a reduction reaction to obtain an intermediate B; and (3) 1,2-dimethylcyclopropane-1,2-
dicarboxylic acid anhydride and the intermediate B undergo two times of
condensation reaction for cyclization and one time of
hydrolysis reaction to obtain the final target product. In the invention, characteristic structure of
procymidone is retained in the synthesized
procymidone hapten such that the
immunogenicity of the procymidone
hapten is obviously enhanced, and the procymidone hapten also has a carboxyl group capable of
coupling with a carrier, thus providing a foundation for subsequently building various
immunoassay methods of procymidone.
