Flash vacuum pyrolysis (FVP) of 3-azolylpropenyl alcohols 5–7, 12 or 15 at 650–700 °C (10–2–10–3 Torr) causes loss of water and cyclisation to give 3H-pyrrolizine 8 and its analogues 9, 10, 13 and 16; at higher temperatures (e.g. 900 °C)

2-(Pyrrol-1-yl)phenoxyl, aminyl, thiophenoxyl and benzyl radicals 2a–2d, respectively, were generated in the gas-phase under flash vacuum pyrolysis conditions. In all cases except the phenoxyl, cyclisation took place providing acceptable synthetic
