A method is proposed for the synthesis of acetylated glycosides of hydroxynaphthoquinones.The condensation of D-glucose and D-galactose (tert-butyl orthoacetate)s with lawsone and lapachol has given the tetra-O-acetyl-β-D-glucopyranosides of lawsone and of lapachol and the tetra-O-acetyl-β-galactopyranoside of lawsone.The structures of the glycosides obtained have been confirmed by IR and 1H and 13C NMR spectroscopy.The structure of the lawsone acetylgalactopyranoside described previously has been corrected.
