Abstract

Procedure for obtaining glucoside derivatives of formula I, **(See formula)** wherein R1 signifies an alkyl radical containing from 1 to 5 carbon atoms, characterized in that a 4'-demethylepipodophyllotoxin derivative of formula II is condensed, **(See formula)** wherein R3 is a substituted or unsubstituted phenyl radical, with a 4,6-O-alkylidene-glucopyranose of formula III, in which R1 has the meaning indicated above, and means the formyl or acetyl radical, in the presence of boron trifluoride in a solvent that is inert under the reaction conditions, and then the protecting radicals are cleaved from the resulting compounds of formula IV, **(See formula)** in which R1, R2, and R3 have the meanings indicated above.
