Abstract

The complete assignments of the ^13^C NMR resonances of 1‐acetyl‐, 1‐benzoyl‐, 1‐benzenesulphonyl‐, 1‐methanesulphonyl‐ and 1‐(2‐nitrobenzenesulphonyl)‐isatins and their ring‐opened glyoxylic derivatives are reported. The ^13^C assignments of acylisatins were derived from isatin as a model, while assignments of glyoxylic derivatives were made by complete assignment of compound 8b together with its use as a model.
