The stereoselective synthesis of non-anomeric sugar β-lactams via [2+2] cycloaddition of achiral ketenes to chiral imines derived from cyclic dialdoses was reported earlier by Palomo and co-workers: C.

In general an excess of aldehyde is employed for the in situ generation of the imine. These conditions are used to avoid the presence of unreacted amine which subtracts part of the ketene.

For a fully automatable procedure, the ketene generation was also carried out by using the highly basic (but quite expensive) BEMP resin (polymer-bound triaminophosphonamide imine) that removes the trialkylammonium salt by-products and therefore simplifies considerably the work-up procedure. Full details of this methodology will be reported in a forthcoming paper. For the earlier use of the BEMP resin for ketene generation, see: A. E. Taggi, A. M. Hafez, H. Wack, B. Young, D. Ferraris, T. Lectka, J. Am. Chem. Soc. 2002, 124, 6626-6635.

The ease of removal of all protective groups from the β-lactam ring and sugar residue by CAN oxidation and hydrogenolysis was demonstrated in compounds (3R,4S)-3b and (3R,4S)-4c.
