"privileged" structure with representation in over 3000 natural isolates and 40 medicinal agents of diverse therapeutic action. A newstrategy for asymmetric access to this important pharmacaphore has been accomplished that involves the amine catalyzed alkylation of indoles with alpha,beta-unsaturated aldehydes. Central to these studies has been the design of a newchiral amine catalyst that exhibits
