The title compounds, variously protected 2.3-anhydrosugars linked with genistein through an alkyl chain, were synthesized in a sequence of reactions. First step involved Ferrier rearragement of 3,4-di-O-acetyl-L-rhamnal with 3-bromopropanol to obtain 2,3-unsaturated bromoalkylglycosides. The next step was epoxidation with m-CPBA and finally these compounds were connected with genistein in reaction of 7-O-genistein tetra-butylamonium salt with 2,3-anhydro bromoalkylglycosides. Obtained glycoconjugates differ in orientation of an oxirane ring and the protecting group in a sugar moiety. All compounds were tested in vitro for antiproliferative potential in cancer cells.
