D-(and L-)2, 6-Dideoxy-2-aminoglycosidic variants of 4'-O-demethyl-1-epipodophyllotoxin were synthesized by glycosidation of 4'-O-benzyloxycarbonyl- or 4'-O-chloroacetyl-4'-O-demethyl-1-epipodophyllotoxin (6 or 14) with the corresponding aminosugar derivatives. 1-O-(2-Amino-2-deoxy-4 : 6-O-ethylidene-β-D-glucopyranosyl)-4'-O-demethyl-1-epipodophyllotoxin (18) reacted with aldehydes in the presence of sodium cyanoborohydride, or reacted with α, β-unsaturated esters, or with α, β-unsaturated nitriles to yield the corresponding N-alkyl analogs. A number of the 4'-O-demethyl-1-epipodopyllotoxin β-D-aminoglycoside derivatives gave significant survival time increases in mice with leukemia L-1210. In particular, 1-O-(2-dimethylamino-2-deoxy-4 : 6-O-ethylidene-β-D-glucopyranosyl)-4'-O-demethyl-1-epipodophyllotoxin (19) showed superior activity to VP-16-213 (etoposide, 1).

D-(and L-)Aminoglycosidic variants of 4'-O-demethyl-1-epipodophyllotoxin were synthesized by glycosidation of 4'-O-benzyloxycarbonyl- or 4'-O-chloroacetyl-4'-O-demethyl-1-epipodophyllotoxin (8 or 22) with the corresponding aminosugar derivatives. Cyclic acetals of 1-O-(2-amino-2-deoxy- and 3-amino-3-deoxy-β-D-glucopyranosyl)-4'-O-demethyl-1-epipodophyllotoxins (13 and 21) gave a significant survival time increase in mice with leukemia L-1210, and showed superior activity to VP-16-213 (etoposide, 5).
