Photochemistry of .alpha.'-substituted .beta.,.gamma.-cyclopropyl cyclic ketones. Influence of geometric constraints and substituent effects on competitive Norrish type I photoreactions
α-aminocyclohexanones has been shown to give cyclopentane carboxylic acids, bicyclo[3,1,0]hexane-2-ones, and 2-methyl-2-cyclopentene-1-ones. Deamination of 3-endo-aminocamphor gave cyclocamphanone, 6-isopropenyl-6-methyl-2-cyclohexen-1-one, and 6- (1′-hydroxy-1′-methylethyl)-6-methyl-2-cyclohexen-1-one.The formation of bicyclo[3,1,0]hexane by deamination of cyclohexylamine is reported for the first time.
