β-Lactones possessing α-branched substituents are not obtained in sufficiently high enantioselectivities from the catalyzed AAC reactions to be generally useful. Lactone 1g was readily prepared from the enzyme-mediated resolution of the racemic β-lactone that was derived from the achiral AAC reaction, see: a) S. G. Nelson, K. L. Spencer, J. Org. Chem. 2000, 65, 1227-1230: see also:

To verify that lactone ring opening was proceeding with rigorous inversion of configuration, the enantiomeric purities of azides 4a-c were determined by chiral-phase HPLC (Chiralcel OD-H column) of the methyl esters derived from 4a and 4b, and the benzyl ester derived from 4c.
