Abstract
The reactions of para-hydroxy-meta-aminobenzene sulfonic acid with methyl esters of acylpyruvic acids were studied. Short-term boiling of equimolar amounts of the initial reagents in acetic acid in the presence of sodium acetate produces sodium salts of 3-acylmethylene-2-oxo-1,4-benzoxazine-6-sulfonic acids, the treatment of which with sulfuric acid leads to 3-acylmethylene-2-oxo-1,4-benzoxazine-6-sulfonic acids. Structure of the compounds was established on the basis of IR and 1Н NMR spectroscopy data. Antimicrobial activity of the obtained compounds was studied.
