Sumnary: N-methyl and other N-alkyl benzimidazoles and benzotriazoles were prepared by 18-crown-6 catalysis involving basic aqueous solutions of the heterocycles and organic solutions of alkyl iodides or bromides. In the course of our work with highly substituted benzimidazoles, we required a mild,

This paper briefly reviews the use of Schiff base substrates in amino acid synthesis. Recent studies lead to the proposal of a new active catalyst species (12) for the asymmetric PTC alkylation of active methylene compounds (2). Mechanistic implications are detailed.
