The Michaelreaction of 1,2-cyclohexanediones with methyl vinyl ketone is highly dependent upon the structure of dione or the catalyst, base or ZnCl2, affording 3-(3-oxobutyl)-2-hydroxy-2-cyclohexen-1-one or 1-hydroxy-7-acetylbicyclo[3.2.1]octan-8-one as major products. 1,2-Cyclopentanediones react with methyl vinyl ketone somewhat differently.
