Flitsch, Wilhelm,Jones, R. Alan,Hohenhorst, Manfred
, p. 4397 - 4398 (1987)
A report is given on the synthesis of 3a-azaazulen-3-ones 2a and 2b.Experiments designed to prepare isomeric 3a-azaazulen-1-ones 1a/b resulted in a formation of rearranged γ-pyridone derivatives 7a/b and a dimer 8 of 1b.
3a-Azaazulenones with a Carbonyl Group in the 5-Membered Ring
Flitsch, Wilhelm,Hohenhorst, Manfred
, p. 449 - 452 (2007/10/02)
Syntheses and properties of unstable 3a-aza-3-azulenones 1 are described.Attempts of a synthesis of 3a-aza-1-azulenones 2 resulted in a formation of rearranged pyridones 10 and a dimer 11 indicating the unstable intermediates 2.
