Abstract
(Salen)manganese(III)-catalyzed oxidation of silyl ethers with iodosylbenzene gave the corresponding carbonyl compounds. The enantioselective oxidation of symmetrical 1,3- and 1,4-disilyl ethers gave the corresponding optically active b- and g-siloxyketones, respectively (up to 93% ee).
Key words
asymmetric oxidation - silyl ethers - manganese catalyst - iodosylbenzene - siloxyketones
