The present invention relates to novel Chartreusin analogues of formula (I), pharmaceutical compositions comprising the same and to their use for the treatment of cancer and other diseases.
Reaction of salicylaldehydes (1) with carbethoxymethylenetriphenylphosphorane in diethylaniline under reflux gave coumarins (3) in moderate to high yield except 3-methoxycarbonylsalicyladehyde (1e) as summarized in Table I. The substituent effects are discussed. A substituent at C6 on 1 usually facilitated the formation of the coumarin ring regardless of its electronic character.
