✦ Synopsis


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.
