Abstract:

Many examples of α,β-diamino acids are found in nature or as components of natural products and their core structure is part of a wide variety of therapeutically useful drugs. 2,3-Aziridino-γ-lactones have been shown to be valuable starting materials for the preparation of a- and b-amino acids. In this work, we wish to report the intramolecular aziridination of sulfamates derived from butenolide 1 as well as its 2-methyl derivative 2 to obtain 2,3- aziridino-γ-lactones. The reactivity of the latter toward nucleophiles and application of the procedure to the synthesis of α,β-diamino acids were subsequently studied.
