| Outline of Final Research Achievements |
The synthesis of 2-indolinones including adjacent quaternary carbon centers was performed by the diastereoselective cascade reaction (olefination-isomerization-Claisen rearrangement) of 2-allyloxy-3-indolinones. The scope and limitation of the cascade reaction were defined. By applying this reaction, the construction of backbone architecture having all carbons of natural product communesin F was achieved. The syntheses of phenserine and 5-N-acetylardeemin derivatives and evaluations of their acetyl-/butyryl-cholinesterase and ABCG2-transporter inhibitory were performed to show their structure–activity relationship study (SARS), respectively. The synthetic route to the related compound isoroquefortine was confirmed for its SARS.
