Abstract
In the phase transfer system solid calcium carbonate-acetonitrile, per acetate alpha-D-glucosaminilchloride glycosilate easily deprotoned isatine-3-oximes hydroxyl groups. It was found that the presence in the reaction mixture a catalytic amounts of 15-crown-5 accelerated the process twice. Obtained O-beta-D-glucosaminides were identified with 1H-NMR spectroscopy. Features of synthesized compound's NMR spectra are discussed in comparison with those of another N-acetylglucosamine 1-O-derivatives. The biological activity of the some oximes with different substituents in isatin residuum has been studied in a test of inhibition of bioluminescence of marine luminescent bacteria Photobacterium leiognathi Sh12. The nature of N-substituent of isatin fragment and 5-substituent of isatin main structure is compared with glycosides ability to suppress bacterial luminescence.
