    Summary:Marine tricyclic alkaloids lepadiformine and fasicularin, with a unique perhydropyrrolo[2,1- j]quinoline or perhydropyrido[2,1- j]quinoline framework, were synthesized starting from the B ring of the tricyclic system. This approach includes a highly stereocontrolled diallylation of a cyclic enaminoester and subsequent ring-closing metathesis to construct the A/B ring system, which was transformed into key lactams 32 and 33, and amino alcohol 37. Thus, we achieved formal syntheses of (-)-lepadiformines A, C, and (-)-fasicularin in a divergent manner.
  • FORMAL SYNTHESIS OF GEPHYROTOXIN 287C, Katsuki Takashima, Naoki Toyooka, HETEROCYCLES, HETEROCYCLES, 99(1), 649 - 660, Apr. 2019 , Refereed
    Summary:The enantioselective formal synthesis of (-)-gephyrotoxin 287C (1) has been achieved from octahydroquinolinone 8. The alpha, beta-unsaturated ester 16, whose enantiomer was a key intermediate for the total synthesis of (+)-1, was synthesized by highly stereoselective Michael-type conjugate addition reaction to 8 and subsequent transformations.
