The known antibiotic daunomycin, and the novel compounds daunomycin-β-anomer and 4'-epidaunomycin (both α- and β-anomers) are prepared by condensing daunomycinone with reactive novel intermediates which are 1-chloro-2,3,6-trideoxy-3-trifluoroacetamido-4-trifluoroacetoxy-α-L-lyxo (or arabino) hexopyranoses. |
