The synthesis and reactivity of 7-azaindolizines.
… 7-azaindolizines have been synthesised via the Chichibabin reaction between suitably substituted methylpyrazines and a-bromoketones. The structures of the products obtained have been confirmed spectroscopically (mainly by pmr spectroscopy) and elemental analysis. Examination of the pmr spectra …

The synthesis and reactivity of 6- and 8-azaindolizines.
… 8- azaindolizines have been synthesised via the Chichibabin reaction between suitably-substituted 2- or 4- methylpyrimidines and alpha-bromo ketones. The structures of the products obtained have been confirmed spectroscopically, principally by 'H NMR spectroscopy, and by formylation procedures. …
