Diversely substituted N-aryl-2-cyanoazetidines can be prepared in high yields from β-amino alcohols in enantiomerically pure form through a three-step sequence involving copper-catalyzed N-arylation, N-cyanomethylation of the secondary aniline, and one-pot mesylation followed by ring closure induced by a base. This method gives access to azetidines with a predictable and adjustable substitution pattern and also with predictable diastereoselectivity.
