英文摘要
Synthetic studies on bioactive natural products, which could be new drugs, were carried out in order to determine their stereochemistry. A new sesquiterpene, potent inhibitor of H. pylori growth, was efficiently synthesized as a racemate via tandem radical cyclization. The stereochemistry of topsentolide A was determined by synthesis of their possible stereoisomers, and cytotoxicity of the synthetic isomers was examined. About Majusculoic acid, a novel antifungal drug, new method to prepare the chiral building block was established.
