Abstract
Description
[0001] This application is a divisional application with an application date of October 14, 2016, an application number of 201610895883.6, and an invention title of "a synthesis method of a diaryl-substituted dicarbonyl compound". technical field
[0002] The invention relates to a synthesis method of a dicarbonyl compound, more particularly to a synthesis method of a diaryl-substituted dicarbonyl compound, and belongs to the technical field of organic chemical synthesis. Background technique
[0003] The carbonyl structure is a very important type of active group in organic chemical synthesis, which can expand and change the group through a variety of reactions, so it plays an important role in organic chemical synthesis. For example, dicarbonyl compounds are a class of highly functional structural units, which are very important in drug design and functional group modification.
[0004] Therefore, the development of synthetic methods for dicarbonyl compounds has attracted ...
Examples
Embodiment 1
[0036]
[0037] In an appropriate amount of organic solvent at room temperature (a mixture of dimethyl sulfoxide (DMSO) and acetonitrile at a volume ratio of 3:1), add 100 mmol of the above formula (I) compound, 120 mmol of the above formula (II) compound, 20 mmol Two-component composite catalyst (composed of 10mmol 1,3-bis(diphenylphosphinopropane) nickel dichloride and 10mmol copper hexafluoroacetylacetonate), 200mmol oxidant 2-iodylbenzoic acid (IBX), 150mmol base dimethyl Aminopyridine (DMPA) and 14mmol auxiliary tetraphenylporphyrin, then heated to 70°C while stirring, and stirred and reacted at this temperature for 9 hours;
[0038] After the reaction is completed, quench the reaction with deionized water, filter, fully wash the filtrate with deionized water, then extract the organic phase with ethyl acetate for 2-3 times, combine the organic phases and dry them with anhydrous sodium sulfate, and finally distill under reduced pressure. The viscous residue obtained was...
