Allylic Oxidations Catalyzed by Dirhodium Catalysts under Aqueous Conditions

Page/Page column 13-14; 19-20, (2009/04/24)
The present invention relates to compositions and methods for achieving the efficient allylic oxidation of organic molecules, especially olefins and steroids, under aqueous conditions. The invention concerns the use of dirhodium (II,II) “paddlewheel complexes, and in particular, dirhodium carboximate and tert-butyl hydroperoxide as catalysts for the reaction. The use of aqueous conditions is particularly advantageous in the allylic oxidation of 7-keto steroids, which could not be effectively oxidized using anhydrous methods, and in extending allylic oxidation to enamides and enol ethers.

Irradiation at λ=366 nm of oxygenated solutions of η3-allylpalladium complexes leads to unsaturated carbonyl compounds.Substitution of the η3-allyl ligand by an electron withdrawing group could induce a regioselective oxidation of the allylic position farthest from this group.The efficiency of these reactions is sensible to the nature of the solvent.
Reactions of 1-Methyl-4-t-butylcyclohexene and 1-Methylcyclohexene with Thallium(I) Acetate-Iodine

Treatment of 1-methyl-4-t-butylcyclohexene (2) with thallium(I)acetate-iodine in wet acetic acid at 90 deg C gives a complex mixture of products, which differs from that obtained from a Woodward reaction with silver(I) acetate followed by hydrolysis and which includes the unexpected hydroxy-iodoacetate (25).At 20 deg C the thallium(I)-mediated reaction gives a mixture of regioisomeric iodo-acetates.A re-investigation of the reaction of thallium(I) acetate-iodine with 1-methylcyclohexene (1) at 20 deg C has shown that this is not highly regioselective as reported earlier.The actions of KOAc-I2-18-crown-6 and iodine(III) triacetate in acetic acid on the alkenes (1) and (2), and of I2-H2O in tetramethylene sulphone-chloroform on the alkene (2) are reported.
