Method for producing jasmonate derivatives and intermediates thereof

摘要

A process for efficiently producing a 2-alkyl-2-cyclopentenone comprising reacting an amine and a hydrogen halide, which are present in a ratio ranging from 1.1:1 to 5:1, with a 2-alkylidene cyclopentanone to carry out an isomerization reaction. A process for producing a jasmonate derivative comprising reacting a 2-alkyl-2-cyclopentenone with a malonic acid diester.
