Versatile and highly efficient synthetic routes leading to optically active cyclobutanones, gamma-amino acids and delta-amino alcohols are described. These compounds are relevant synthetic precursors to enantiopure cyclobutane carbocyclic nucleosides and oligopeptides. (-)-(S)-Verbenone is the chiral starting material used and the key synthetic steps involve concerted rearrangements in acidic medium. (C) 2003 Elsevier Science Ltd. All rights reserved.
