Preparation method of 2-acyl-3, 4-dihydronaphthalene derivative |
| abstract |
The invention discloses a novel preparation method of a 2-acyl-3, 4-dihydronaphthalene derivative. The method takes a methylene cyclopropane compound and an alpha-keto acid compound as reaction raw materials, and prepares a series of 2-acyl-3, 4-dihydronaphthalene derivatives with high yield by reacting in a cheap silver catalytic oxidation reaction system. The method has the advantages of wide reaction substrate adaptation range, mild operation conditions and high yield of the target product. |
