Cleavage of isoxazolines to fi-hydroxy ketones.1 This cleavage can be effected with either 3,5-dinitroperbenzoic acid (1) or trifluoroperacetic acid using about 5 equiv. of the peracid at 25°. Use of more drastic conditions results in Baeyer-Villigar oxidation of the p-hydroxy ketones to acylated diols. 

The diene (117) has been epoxidized with 3,S-dinitroperbenzoic acid (equation 43). Attack at both the double bonds is stereoselective. Epoxides of enol ethers are normally difficult to isolate, but the epoxide (118) is quite stable. This staUlity is due to the attachment of the electron-withdrawing carb-... 

Oxidations - 3,5-Dinitroperbenzoic acid is a stable storable peracid equivalent in activity to trlfluoroperacetic acid. A full paper has appeared which gives the experimental details for the a-hydroxylation of carbonyl compounds by treatment of the anions of enol silanes with Mo05 HMPA (MOOPH). Anions from carboxylic esters (LiN(iPr)2>LDA -78°C) can be efficiently, regiospecifically chlorinated or brominated by treatment with respectively CCl or CBr. Treatment of enol silanes from conjugated ketones with m-chloroperbenzolc acid (MCPBA) followed by removal of silicon affords the a-hydroxyketones. ... 

The key lactone 1 was synthesized in high yield starting with 3-cyclohexenecarboxylic acid 2. lodolacto-nization and elimination afford the allylic lactone 4 and epoxidation with 3,5-dinitroperbenzoic acid provides exo epoxide 5 with high stereoselectivity. This epoxide...
