The FeCl 3 -mediated condensation of an α-phenylenamino ester and an enone proceeds efficiently to afford a 2-phenylnicotinate. The subsequent intramolecular Friedel-Crafts reaction yielded an onychine framework. Modifications at the 2-, 3-, and 8-positions of the onychine framework were easily achieved by altering the enamino esters and enones, which facilitated the discovery of potentially bioactive compounds.

1-Methyl-3-phenyl-4-azafluorene was obtained by intramolecular cyclization of 2,4-dibenzoyl-3-methylbutene by the action of sulfuric acid followed by closure of the pyridine ring in the obtained 2-(3-oxo-1-methyl-3-phenylpropyl)-1-indanone by the action o
