Abstract

The effect of different Michael acceptors was evaluated in the catalytic asymmetric intramolecular Stetter reaction. Utilizing a readily prepared chiral triazolium salt as a nucleophilic carbene precursor, the reactivity and selectivity of substrates containing different electron-deficient double bonds was shown to vary significantly under identical reaction conditions.
