Remote transmission: In the presence of chiral amines, 2,4-dienones are activated toward the attack of a nucleophile at the a position, a mode of activation that is termed vinylogous iminiuma ion catalysis. Specifically, the 1,6a addition of alkyl thiols to β-substituted cyclic dienones was catalyzed by a cinchona-based primary amine; the reaction was highly stereoselective and displayed high selectivity for reaction at the a position.
