Concise Approach to Mono- and Disubstituted Luotonin A Analogs and Their Cytotoxicity Test
摘要:
A concise approach for the preparation of luotonin A analogs has been developed. The new synthetic route contains an anion-assisted intramolecular double hetero Diels-Alder reaction and a direct oxidative cross coupling reaction. Some synthetic luotonin A analogs show cytotoxic activities against Daudi and Jurkat human cancer cells as potent as camptothecin.

The palladium-catalyzed three-component cycloaminocarbonylation of 2-formylaryl tosylates with hydrazines and carbon monoxide has been established, which provides an efficient method for synthesis of substituted phthalazinones. In addition, by applying this protocol as the key step, Hydralazine can easily be synthesized in 65% yield.
