Intramolecular cyclisation of suitably constituted nitrocompounds to give N\_-heterocycles has been effected with various reducing agents such as metal oxalates (l), triethyl phosphite (2) and iron pentacarbonyl (3). We have, however, shown that such ring-closures can be carried out by simply heatin
