new therapies is dire. The syntheses of a focused library of hydroxamates and hydroxamic acids is described, as well as anti-TB activity in the microplate alamar blue assay (MABA). A number of compounds exhibited good activity against Mtb, with notable compounds exhibiting MIC values in the range of 20–0.71 μM. This work suggests that both hydroxamates and their free acids may be incorporated into more

The synthesis of a small set of β-lactams containing isocyanate precursors is described. The release of the isocyanate precursor in model hydrolysis experiments was substantiated by trapping experiments, thus confirming that β-lactams can be designed that are capable of releasing alternatively reactive species. Preliminary biological assessments are also briefly discussed.

parallel synthesis of hydroxamic acids from carboxylic acids and hydroxylamine in good to high yields is reported. It involves the formation of a polymer-bound HOBt active ester and subsequent reaction with O-protected or free hydroxylamine. The hydroxamates are isolated with high purities by simple evaporation of volatile solvents. The use of free hydroxylamine leads to increased yields while maintaining
