The structural analogy of 1,3-dicarbonyl compounds with 2-hydroxybenzencarbonyl compounds allowed to do an analysis towards the reactivity with 3-aminophenylboronic acid, in order to evaluate the synthesis of macrocyclic boron compounds having calixarene like structures. The results indicate that the chelate form is preferred over the reaction of the amino group with carbonyl groups. Thus the reaction of 1,3-diketones (1,3-diphenyl-1,3-propanedione, 1-phenyl-1,3-butanedione and 2,4-pentanedione) with 3-aminophenylboronic acid using methanol or propanol as solvent medium, afforded the six-membered boron chelates as the only product.
The reactivity of 1,3-diketones toward 3-aminophenylboronic acid was evaluated, spectroscopic analysis showed the formation of heterocyclic six-membered boron compounds.Figure optionsDownload as PowerPoint slide
