Description
Technical Field
The invention relates to the technical field of organic synthesis, in particular to a method for preparing 1-cyclopropyl naphthalene.
Background
1-cyclopropyl naphthalene is an important organic molecular skeleton and widely exists in chemical raw materials and pharmaceutically active molecules. At present, a method for synthesizing 1-cyclopropyl naphthalene is reported, and mainly comprises the following steps:
firstly, the catalyst is prepared by coupling reaction of cyclopropylboric acid and halogenated naphthalene under a palladium catalyst, wherein the reaction equation is as follows, and the method needs noble metal and methylboric acid, has high cost and is not beneficial to industrialized mass production;
the bis-cyclopropyl metal reagents (e.g., lithium, magnesium) and the halonaphthalenes are prepared by palladium or nickel catalyzed coupling. The method also uses noble metals and high-activity metal reagents, and is not beneficial to industrial mass production.
Thirdly, the 1-vinyl naphthalene and the dihalomethane are subjected to cyclization under the action of strong alkali tert-butyl magnesium chloride to obtain the 1-cyclopropyl naphthalene, wherein the reaction equation is as follows, and the method uses a high-activity metal reagent, so that the method is not beneficial to industrial mass production.
In summary, the existing methods use either noble metals and expensive methyl boric acid or high-activity metal reagents, which results in high production cost, complex operation and extremely high risk, and are unfavorable for industrialized mass production. Meanwhile, a great amount of metal residues and a great amount of solid wastes bring great pressure to the purification and environmental protection of the compounds.
Therefore, the development of a new method for preparing 1-cyclopropyl naphthalene, which is more suitable for industrial production, has important significance.
