Methyl 3-O-(3,6-anhydro-beta-D-galactopyranosyl)-alpha-D-galactopyranoside (3) and methyl 3,6-anhydro-4-O-beta-D-galactopyranosyl-alpha-D-galactopyranoside (4) have been synthesised stereoselectively using three coupling procedures. Acceptable yields were achieved using acetylated derivatives as don
## Abstract The synthesis of the title compound (5) is described. Treatment of 4‐O‐(4,6‐ethylidene‐α‐D‐glucopyranosyl)‐4′‐demethyl‐4‐epipodophyllotoxin with sodium metaperiodate in acetonitrile formed the highly colored 4‐O‐(4,6‐ethylidene‐α‐D‐glucopyranosyl)‐3′,4′‐dioxo‐4‐epipodophyllotoxin (1). H
