On the Formation of N-Heterocycles by Thermolysis of Conjugated α-Azidoacrylates

The synthesis of various o-butadienyl-α-azidocinnamates 2 and β-cycloalkenyl-α-azidoacrylates 9 is described.The thermolysis of compounds 2 in solution yields the new 8,9-benzo-6-azabicyclonona-3,6,8-trienes 3 as major products, while that of 9 yields the cycloalkano-2H-pyrroles 10, which can rearrange to the cycloalkano-1H-pyrroles 11 at higher temperatures.A β-(o-vinyl)phenanthryl-α-azidoacrylate 12 was found to react on thermolysis both as a β-cycloalkenyl-α-azidoacrylate and a o-vinyl-α-azidocinnamate. - Keywords: α-Azidoacrylates, thermolysis of / α-Azidocinnamates, thermolysis of / 1H-Pyrroles / 2H-Pyrroles

Intramolecular reactions of α-azidocinnamates with 4-substituted 1,3-dienes

The synthesis of new 8,9-benzo-6-aza-bicyclo[3.2.2]nona-3.6.8-trienes 14 by intramolecular reaction of α-azidocinnamates 9 with alkyl- and phenylsubstituted ortho-butadienyl side chains is reported, as is the formation of the new 1-aza-2-carbomethoxy-7,8-benzo-tricyclo[4.30.02,9]nona-4,7-diene 15.
