Introduction of Oxygen Functions into the α-Position of β-Diketone, 4. Direct Acyloxylation of 1,3-Cyclohexanediones by Diacyl Peroxides

Direct acyloxylation of 1,3-cyclohexanediones 1 leads only by way of exception to the formation of monoacyloxylated products 4.However, their sodium salts 5 yield exclusively the immediate reaction products 8 of a bisacyloxylation.On the other hand, these products are unstable in the presence of base, and they experience a migration of an acyl group and loss of one mol of carboxylic acid yielding cyclohexadienones 9.The mechanism of this new rearrangement is described.Starting from products of a benzyloxycarbonyloxylation a convenient synthesis of reductones is described.
