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