Palladium-catalyzed cyclization of alkenyl beta-keto esters in the presence of chlorotrimethylsilane.
PdCl2(CH3CN)2 catalyzed the cyclization of alkenyl beta-keto esters in the presence of a stoichiometric amount of SiMe3Cl to form 2-carboalkoxycyclohexanones in good yield with excellent regioselectivity.
