Organocatalysis has received considerable attention in the past 10 years [1] and is becoming an exciting area of research, particularly as organocatalytic transformations are now being considered in the design of syntheses of complex natural products [2] and drugs.[3] Most of the organocatalytic reactions involve two basic activation routes: enamine catalysis [4] and iminium catalysis.[5] More recently, the combination of oxidants in the ...
