Research Abstract |
New synthetic organic reaction has been developed and it has utilized for the synthesis of some natural products. Thus, optically active tetrrahydropyran, tetrahydrofuran, and piperidine rings have been prepared selectively by Pd(II)-catalyzed reaction. The reaction mechanism was proposed and proven on the basis of experimental evidence. For the synthesis of tetrahydroisoquinoline, Bi(OTf)_3 was found to be effective as a Lewis acid catalyst. Anti-cancer natural product(-)-apicularen A as well as natural alkaloid(-)-trolline and others have been synthesized.
