    There are only a few methods for the asymmetric ring expansion of prochiral ketones. Symmetrically substituted cyclohexanones can be converted to the corresponding ring-expanded caprolactam with excellent 1,7-diastereoselectivity (≥93% ds) and yields (≥86%), using a chiral hydroxy azide-mediated Schmidt reaction.
