| titleOfInvention | USEFUL COMPOUNDS IN THE PREPARATION OF CAMPTOTECHINE DERIVATIVES. |
| abstract | Novel compounds are provided having formula (1) and salts thereof, wherein R 1 is hydrogen, an alkyl, aralkyl, hydroxymethyl, carboxymethyl, acyloxymethyl or trialkylsilyl group, or a -CH 2 NR 3 R 4 group where N is a nitrogen bonding atom and where (a) R3 and R4 are independently selected from the groups of hydrogen and alkyl, alkenyl, hydroxyalkyl and alkoxyalkyl; (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 binding nitrogen atom form a saturated 3- to 7-membered heterocyclic group. These compounds are useful intermediates in a process to prepare camptotecin derivatives including the anti-cancer drug irinotecan. |
