We developed an efficient method for the synthesis of 3-substituted 2,3-dihydroquinolin-4-ones using a one-pot sequential multi-catalytic process: Pd-catalyzed allylic amination-thiazolium salt-catalyzed Stetter reaction cascade. Measurement of the initial rate of the developed sequential process revealed a significant increase in the reaction rate of the Stetter reaction in the presence of Pd(OAc)(2) and AcOH center dot i-Pr2NEt, the constituents of the first Pd catalysis.
