AZEPINONES. PART 4.1,2 ELECTROCYCLIC AND CYCLOADDITION REACTIONS OF 1H-AZEPIN-3(2H)-ONES

Photolysis of the azepinone (2) gives the bicyclic photoproduct (5) in 64percent yield; this compound reverts cleanly to the starting material (2) on thermolysis in toluene.Cycloaddition reactions of the azepinones (1) or(2) with maleic anhydride generate the endo adducts (7) or (8), respectively, whereas treatment of (1) with acetylenic dienophiles gives rise tobenzenoid compounds after cleavige of the three-atom bridge.

Azepinones. Part 1. Formation of simple 1H-azepin-3(2H)-ones by gas-phase pyrolysis: Crystal and molecular structure of 1-phenyl-1H-azepin-3(2H)-one

Flash vacuum pyrolysis of the Meldrum's acid derivatives (4) - (6) at 500 °C (10-3 Torr) gives good yields of the 1H-azepin-3(2H)-ones (7) - (9) respectively. X-Ray crystallography of the 1-phenylazepinone (8) shows that the dienaminone conjuga

Thermal Cyclisation Reactions of Vinylogous Aminomethylene Meldrum's Acid Derivatives

Flash vacuum pyrolysis of vinylogous aminomethylene derivatives of Meldrum's acid leads to new cyclisation reactions; one additional double bond results in the formation of 1H-azepin-3(2H)-ones, while two additional double bonds lead to benzamide derivatives.
