Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The first example of C alkylation of 1, 2‐dihydropyridines with alkyl triflates and Michael acceptors was developed to introduce quaternary carbon centers with high regio‐ and diastereoselectivity. Hydride or carbon nucleophile addition to the resultant iminium ion also proceeded with high diastereoselectivity. Carbon nucleophile addition results in an unprecedented level of substitution to provide piperidine rings with adjacent tetrasubstituted carbon atoms.</p> </abstract>
