摘要
The oxidation of 1,3-dicarbonyl compounds with (camphorylsulfonyl)oxaziridines 2 was studied in both cyclic and acyclic systems. Two reaction pathways were identified: enolate alpha-hydroxylation and a novel Baeyer-Villiger type oxidation. The Baeyer-Villiger oxidation product was observed only for the ketones and arises via rearrangement of an alkoxy epoxide. Synthetically useful ee's (82-95%) were observed only for enolates of beta-ketoesters where the keto group is part of a 6-membered ring. (C) 1998 Elsevier Science Ltd. All rights reserved.
