The syntheses of 2‐ 13 C and 3‐ 13 C indoles and indolizines and 1‐ 13 C indolizine are described. They are obtained from 1‐ 13 C bromoacetaldehyde on (2‐pyridyl) ethylacetate for 2‐ 13 C indolizine, and through cyclisations of suitably labelled intermediates:o‐formotoluidide for 2‐ 13 C indole, o,β‐dinitrostyrene for 3‐ 13 C indole, and 3‐(2‐pyridyl)‐1 propanol for 3‐ 13 C and for 1‐ 13 C indolizines. Every position is more than 90% 13 C‐ labelled.
