Problems solved by technology

[0012] These synthetic methods use perodane, which is expensive and difficult to synthesize, as the main intermediate for the synthesis of acryloyldane. There are many synthetic steps for the required reaction, complex operations, low yield, expensive raw materials, and harsh process conditions. Greatly limit the application of acryloyl dan and its analogues

Abstract

The invention belongs to the technical field of synthesis of fluorescent probes in biochemistry, and particularly relates to an environment-sensitive fluorescent probe and a synthesis process route of Acrylodan and analogues thereof. A method comprises the following steps: taking 6-methoxy-2-acetyl naphthalene as a raw material, carrying out substitution reaction on the 6-methoxy-2-acetyl naphthalene and a lithium amide salt, carrying out addition elimination reaction on an obtained amino-substituted acetyl naphthalene product and trifluoroacetic acid, and then carrying out addition elimination reaction on the obtained amino-substituted acetyl naphthalene product and aldehydes to finally obtain the high-purity Acrylodan compound and analogues. The method has the advantages of simple synthesis steps, short reaction time, high yield, low production cost and the like, and solves the problems of complex synthesis steps, harsh synthesis conditions and expensive synthesis raw materials in original synthesis methods. The optimization and improvement of the synthetic process route of Acrylodan and analogues can greatly promote the application of the environment-sensitive probe in the field of biochemistry.
