Description
Technical Field
The invention belongs to the field of fluorine-containing compounds, and particularly relates to a (4E) -1-fluoro-2, 5-diaryl-4-pentene-2-alcohol derivative and a synthesis method thereof.
Background
Fluorine has large electronegativity and small radius, and the introduction of fluorine atoms or fluorine-containing groups into organic molecules can effectively change the physicochemical properties of the organic molecules, so that the fluorine-containing compounds have very wide application in the fields of biological medicine, pesticide, material science and the like. It was investigated that the fluorine-containing compounds in all agricultural chemicals accounted for about 30% and the fluorine-containing compounds in the pharmaceuticals accounted for about 20%. Fluorinated materials have been widely used in liquid crystal displays. In addition, fluorine-labeled molecular probes can also be used for the diagnosis of diseases. Therefore, in order to satisfy the urgent needs of research and search for fluorine-containing compounds and the increasing kinds and amounts of fluorine-containing compounds, efficient synthesis of fluorine-containing compounds is one of the problems that chemists have urgently needed to solve.
The cross-coupling reaction among molecules is one of the important methods for constructing C-C bond, and the Heck reaction for obtaining the chemical prize of Nobel in 2010 is the construction of C (sp)2)-C(sp2) A key. However, this method is generally limited to activated electron deficient olefins, but coupling reactions are difficult to occur with unactivated olefins. Therefore, developing a method for efficiently reacting an unactivated olefin with an aryl group is still a challenging research topic.
Disclosure of Invention
In view of the above disadvantages and shortcomings of the prior art, the present invention is primarily directed to a method for efficiently synthesizing (4E) -1-fluoro-2, 5-diaryl-4-penten-2-ol derivatives.
Another objective of the invention is to provide a method for synthesizing the (4E) -1-fluoro-2, 5-diaryl-4-penten-2-ol derivative.
