Reaction Steps
In a manner similar to that described for 10-nitro-20(RS)-camptothecin, a mixture of 2-amino-4-nitrobenzaldehyde is treated with the tricyclic ketone 11 yielding 11-nitro-20(RS)-camptothecin which in turn is reduced to 11-amino-20(RS)-camptothecin by palladium/carbon. Alternatively, the 11-amino-20(RS)-camptothecin is obtained by reaction of 2,4-diaminobenzaldehyde with ketone 11.
