Novel compounds are provided having formula (I) and salts thereof, where R1 is hydrogen, an alkyl, aralkyl, hydroxymethyl, carboxymethyl, acyloxymethyl or trialkylsilyl group, or a group -CH2NR3R4 where N is a linking nitrogen atom and where (a) R3 and R4 are independently selected from hydrogen and alkyl, alkenyl, hydroxyalkyl and alkoxyalkyl groups; (b) R3 is hydrogen or an alkyl, alkenyl, hydroxyalkyl or alkoxyalkyl group, and R4 is -COR5 where R5 is hydrogen or an alkyl, alkenyl, hydroxyalkyl or alkoxyalkyl group; or (c) R3 and R4 taken together with the linking nitrogen atom form a saturated 3- to 7-member heterocyclic group. These compounds are useful intermediates in a process to prepare camptothecin derivatives including the anti-cancer drug irinotecan.
