| titleOfInvention | Improvements process for chemical reactions on camptothecin or analogs thereof |
| abstract | A process for preparing a reduced camptothecin derivative in which a camptothecin substrate bearing a reducible substituent is hydrolyzed under alkaline conditions to open the lactone E ring and form a carboxylate salt. The carboxylate salt is reduced to form a reduced carboxylate salt which is then contacted with acid to reform the lactone E ring. This procedure results in substantially increased yields of camptothecin derivatives. |
