The synthesis of some monocyclic beta-lactams (monobactams) by the Staudinger reaction using D-glucosamine propanedithioacetal as chiral auxiliary is reported. The influence of several radicals at C-3, C-4, and C-1' (sugar moiety) as well as other structural aspects are considered in relation to the antielastase activity. (C) 1999 Elsevier Science Ltd.
