摘要：
A catalytic domino reaction producing substituted 2-alkylidene-cyclohexanone from 3-oxymethyl-2-siloxy-1,3-butadienes, which can be prepared from Baylis-Hillman adducts, and alpha, beta-unsaturated ketones is described. The process involves two mechanistically distinct reactions, (4+2) cycloaddition and elimination. Both of these reactions are catalyzed by Tf2NH.
