New tricyclic quinoxalinone skeletons with a fully‐reduced ring ‘C’ ‐1,2,3,3a‐tetrahydropyrrolo[1,2‐α]quin‐oxalin‐4‐one (I‐II) and 7,8,9,10‐tetrahydropyrido[1,2‐α]quinoxalin‐6‐one (III‐IV) derivatives were obtained by selective hydrogen transfer reductive cyclisation of N ‐(2‐nitrophenyl)pyrrolidine‐2‐carboxylic acid esters and N ‐(2‐nitrophenyl)piperidine‐2‐carboxylic acid esters (VIa,b and VIIIa,b), respectively.
