What are the synthesis methods of 5-amino-2,4,6-triiodo-3, 5-dihydroxycarbonylbenzene
5 - amino - 2,4,6 - triiodo - 3,5 - dihydroxycarbonylbenzene, Chinese name or 5 - amino - 2,4,6 - triiodo - 3,5 - dihydroxycarbonylbenzene. The method of synthesizing this compound is not detailed in ancient books, but according to today's chemical principles, one or two can be deduced.
First, you can take an appropriate benzene derivative as the starting material. If you find a benzene ring with a modifiable group, such as benzaldehyde, through a clever reaction, iodine atoms are introduced at a specific position in the benzene ring. The introduction of iodine atoms, or the use of iodizing reagents, under suitable reaction conditions, such as specific temperatures and the presence of catalysts, allows iodine atoms to replace hydrogen atoms on the benzene ring, gradually achieving a 2,4,6-triiodine pattern.
Then, dihydroxycarbonyl groups need to be introduced at the 3,5 positions of the benzene ring. This step may be achieved by a specific carbonylation reaction, first introducing carbonyl groups, and then trying to introduce hydroxyl groups at the ortho-position of the carbonyl groups. For example, a suitable metal-organic reagent interacts with a carbonyl-containing reactant to form a carbon-carbon bond, and then introduces the desired functional group. After the carbonyl group is introduced, the hydroxyl group can be introduced into its ortho position by oxidation or hydrolysis to form the structure of 3,5-dihydroxycarbonyl.
As for the introduction of amino groups, the benzene ring can have the above iodine, carbonyl and hydroxyl groups. On the basis of the above iodine, carbonyl and hydroxyl groups, the nitro group is introduced first through nitration reaction, and then the nitro group is reduced to amino group by reduction method, such as the combination of metal and acid, or catalytic hydrogenation, etc., and the final result is 5-amino-2,4,6-triiodo-3,5-dihydroxycarbonylbenzene.
All the above methods require fine regulation of the reaction conditions so that each step of the reaction occurs as expected, in order to successfully synthesize this compound. Although the ancients did not understand this method of synthesis, today's chemical techniques can point the way for exploring the method of synthesis.
