Primary and secondary enaminones derived from cyclohexane-1,3-dione, dimedone, and acetylacetone react with cyclohexenone to give exclusively C-alkylated derivatives. In every case the products form carbinolamines which exist as 1-hydroxy-2-azacyclo[3.3.1]nonenes. This was confirmed in some examples by formation of an extra ring between nitrogen and oxygen. A series of dienaminones were prepared from
