non-deformylating transdiazotization of acylacetaldehydes was achieved: the reactions of 2-azido-l-ethylpyridinium tetrafluoroborate (4) with acylacetaldehydes 3 proceeded partially without deformylation to yield 16 new α-diazo-β-oxoaldehydes 1 along with diazomethyl ketones 2, especially in the presence of NaOAc (Scheme 1, Tables 1 and 2). The product distribution was substituent-dependent and could

In this study, alpha-diazo-beta-oxoaldehyde compounds were condensed with different amines to yield 4-acyl-1H-1,2,3-triazole derivatives. The 1,2,3-triazole compounds were investigated for their inhibition activities against tuberculosis.
