Paragraph 0034-0040, (2020/08/18)
The invention belongs to the technical field of pharmaceutical and chemical intermediates and related chemistry, and provides a preparation method of a 1, 5-diene derivative. The method comprises thefollowing steps: taking aryl substituted propyne and allyl boron ester as reaction raw materials, adopting 2-10mol% of a palladium catalyst, adding 2mol%-20mol% of acid and 100mol%-300mol% of alcoholas additives, and performing heating and stirring in an organic solvent for a certain period of time to generate the 1, 5-diene compound. The method disclosed by the invention has the beneficial effects that the operation is simple and convenient, the condition is mild, the method is environment-friendly, the catalyst can be recycled, the possibility of industrialization is realized, and the 1, 5-diene compound is obtained at a relatively high yield; and the 1, 5-diene compound synthesized by the method can be further functionalized to obtain various compounds, and is applied to development and research of natural products, functional materials and fine chemicals.
