| Research Abstract |
Formal syntheses of microtubule-stabilizing agents, discodermolide and laulimalide were achieved.
Synthesis of discodermolide was started from dimethyl (R)-malate by using chemo-and stereoselective dirhodium catalyzed C-H insertion reaction and novel acceleration technique of Baeyer-Villiger reaction of sterically hindered ketones as key steps to give (2S)-2-tert-butyldimethylsilyloxy-3-[(2S,3S,4S,5R)-4-tert-butyldimethyl-silyloxy-3, 5-dimethyl-6-oxotrahydropyran-2-yl]propanal, Smiths intermediate of their total synthesis of discodermolide. Formal synthesis of laulimalide was included oxonium ylide formation-[3,3]-sigmatropic rearrangement reaction and SN type cyclization as key steps.
