Cyclisation of 5, 8, 10a and 10bvia their lithium derivatives followed by in situ reduction with lithium aluminium hydride gives pyrroloindolenines 2 and 9 and pyridinoindolenines 11a and 11b, respectively.

Cyclisation of 3 and 10 by lithium–halogen exchange followed by reduction with lithium aluminium hydride gives pyrrolo[1,2-a]indoles 11 and 13 respectively. Similar treatment of bromides 4a and 4b gives pyrido[1,2-a]indoles 12a and 12b.
