diastereoisomeric methyl 2,4,6-trideoxy-4-trifluoroacetamido- l-hexopyranosides have been synthesized. Coupling of the corresponding 1- O -acetyl-3- O -benzoyl- l - lyxo and 1- O -acetyl-3- O - p -nitrobenzoyl- l - arabino derivatives with daunomycinone in the presence of p -toluensulfonic acid as catalyst afforded two new anthracyclines.
