✦ Synopsis

After the oxidation of lactose by bacteria of the genus Agrobacterium'4, catalysed by the enzyme hexopyranoside cytochrome c oxidoreductase5, "3-ketolactose" [4-~-(B-D-xy~o-hexopyranosyl-3-ulose)-D-glucopyranose, l] was isolated from the cul-

## Abstract The 1‐NH structure for 3‐azidoindazole has been demonstrated by the observation of ^1^H^1^H and ^13^C^1^H couplings involving the hydrogen atom attached to nitrogen. A comparison between 3‐azidoindazole and indazole shows that both compounds have the same tautomeric structure.
