In this very active field, Michrowska and List applied the combination of iminium-catalyzed 1,4 hydride addition and subsequent intramolecular 1,4 Michael addition for the one-pot synthesis of ricciocarpin, a molluscicidal natural product isolated from the liverwort Ricciocarpos natans (Scheme 11.29). This cascade reaction could be initiated by the single imidazolidinone (I )-3 that catalyzed both imi-nium hydride addition and Michael addition. Treatment of the Michael adduct with Sm(0/-Pr)3 induced the epimeriza-tion of the aldehyde carbon center to the more thermodynamically stable trans ring junction and subsequent Tishchenko reaction (redox process between the aldehyde... [Pg.333]
