| titleOfInvention | Preparation method of methyl dihydrojasmonate |
| abstract | The invention discloses a high-efficiency synthesis method of methyl dihydrojasmonate, which comprises the steps of carrying out Pauson-Khand reaction on 1-heptyne and ethylene under the catalysis of homogeneous rhodium and organic nitrogen oxide to quickly and efficiently obtain 2-pentyl-2-cyclopentenone, and then carrying out addition and decarboxylation on an intermediate by dimethyl malonate to obtain a methyl dihydrojasmonate product. The method has the main advantages that the use of the organic nitrogen oxide effectively improves the reaction yield of the 1-heptyne and the ethylene Pauson-Khand, and simultaneously reduces the dosage of the rhodium catalyst. Compared with the traditional production method of methyl dihydrojasmonate, the method has the advantages of short steps, high atom economy and low cost, and is suitable for large-scale production of methyl dihydrojasmonate products. |
