Paragraph 0068-0070; 0079; 0081, (2020/12/31)
The invention relates to a preparation method of deuterated crizotinib and derivatives thereof, and belongs to the technical field of synthesis of medical compounds. Four deuterated crizotinib with different configurations are synthesized, the influence of the deuterated position and different chirality of the deuterated crizotinib on the biological activity and the drug metabolism property of thecrizotinib is investigated, and the result shows that the deuterated crizotinib and the crizotinib have similar anti-cancer activity. Compared with a deuterated crizotinib raceme and crizotinib, thedeuterated crizotinib has certain physicochemical property advantages, has good anticancer application prospects, and provides a new compound for synthesis of novel antitumor drugs. The resolution ofthe racemate phenylethanol derivative is a key step for synthesizing the deuterated crizotinib, the ee value of the racemate phenylethanol derivative directly influences the ee value of a final product, and the resolution method has the characteristics of easiness in operation, low cost and the like.
