Abstract
Using the Koenigs-Knorr method two isomeric monohydroxynaphthoquinones were glucosidized, i.e. 2-hydroxy-1,4-naphthoquinone (lawson, Ia) and 5-hydroxy-1,4-naphthoquinone (juglone, IIa). The structure of the corresponding glucosides Ib and IIb was proved by 1H NMR, mass, UV, VIS and IR spectra.
