Outline of Final Research Achievements |
Toward synthetic study towards antitumor antibiotic lomaiviticin A with dimeric structure, the synthesis of the substrate for the dimerization was explored, which has a structurally flexible 2-aryl cyclohexane derivative before the construction of 5-membered B-ring with suitable solubility for dimerization condition. Substrate for the dimerization was obtained with Suzuki coupling of bromocyclohexenone and Nagata reagent but dimerization at a desired position was not observed. On the other hand, D ring construction from cinnamic acid ester and furanone was achieved by Michael-Dieckmann continuous reaction.
