    • Convenient conditions, however, for N-arylation of indole-2-carboxylic acid esters have been reported. See: ref. [31]. Nevertheless, this procedure was not attempted since the indolo[1,2-a]quinoxalinones 56 and 57 expected from the reduction/cyclization of N-arylindole-2-carboxylic acids or their esters could be prepared alternatively from the corresponding dihydro derivatives 37 and 43.

    • To simplify discussion, these compounds have been numbered here as the isolated 2-quinoxalinone ring; real numbering of fused compounds can be seen in the description of each product (see Exp. Sect.).

    • 1H NMR spectroscopy and EI MS of the crude material, this by-product seems to be a 1-[2-(2-formylphenyl)-ethyl]quinoxaline-2,3-dione arising from oxidative breaking of the 6a-7 double bond of compound 6.
