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 α-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 β-ketoesters where the keto group is part of a 6-membered ring.
Asymmetric oxidation of β-ketoesters with benzoyl peroxide; enantioselective formation of protected tertiary alcohols

Asymmetric oxidation of β-ketoesters by the benzoyl peroxide quench of their lithioenamines formed with (S)-valine t-butyl esters has been accomplished with good enantioselectivity for the formation of tertiary benzoate esters. This procedure thus enables generation of tertiary alcohols in protected form.
