These new camptothecin derivatives are prepared by treating a 5-R.sup.1 -7-R.sup.2 -camptothecin derivative with a peroxidant and then reacting the resultant 5-R.sup.1 -7-R.sup.2 -camptothecin-1-oxide with an active hydrogen compound under irradiation of UV-rays or by catalytically hydrogenating the ring B of camptothecin in a solvent, treating the resultant tetrahydro product with an acylating agent, introducing a nitro group into the 10-position of the acylated product by the reaction with nitric acid, splitting off the acyl group in the 10-nitro product by hydrolysis and treating the hydrolyzed tetrahydro product with an oxidizing agent for dehydrogenation, and if desired, reducing the nitro group in the resulting product to an amino group and modifying the amino group by N-alkylation, N-acylation or by diazotization followed by hydrolysis or the Sandmeyer reaction, before or after the oxidation of the 10-nitro-tetrahydro product.
