The synthesis of some monocyclic β-lactams (monobactams) by the Staudinger reaction using d-glucosamine propanedithioacetal as chiral auxiliary is reported. The influence of several radicals at C3, C4, and C(1') (sugar moiety) as well as other structural aspects are considered in relation to the antielastase activity.

2-Deoxy-D-arabino-hexose and some N-protected 2-amino-2-deoxy-D-glucose derivatives were each treated with 2,2-dimethoxy- or 2,2-dibenzyloxy-propane in 1,4-dioxane in the presence of p-toluenesulfonic acid at 60-70 deg.The major products were acyclic, dim
A SIMPLE PREPARATION OF 2-(ACYLAMINO)-2-DEOXY-3,4:5,6-DI-O-ISOPROPYLIDENE-aldehydo-D-GLUCOSE DIMETHYL AND DIBENZYL ACETAL

When treated with a large excess of 2,2-dimethoxypropane or 2,2-dibenzyloxypropane in 1,4-dioxane solution in the presence of p-toluenesulfonic acid, 2-acetamido-2-deoxy-D-glucose and 2-(benzyloxycarbonylamino)-2-deoxy-D-glucose yield the corresponding 3,4:5,6-di-O-isopropylidene-aldehydo-D-glucose dimethyl or dibenzyl acetal in good yield.
