An enantioselective catalytic synthesis of α-acetoxylated ketones through I(I)/I(III) catalysis using a resorcinol/lactamide-based chiral iodoarene is reported. Catalyst turnover by in situ generation of the active iodine(III) derivative is achieved by oxidation with mCPBA in the presence of acetic acid. The prior transformation of ketones to easily accessible acetyl enol ethers is beneficial and yields up to 97 percent with enantioselectivities up to 88 percent ee are obtained using only low catalyst loadings of only 5 mol percent under mild reaction conditions.

Oxazoline compounds having a 2,6-disubstituted-phenyl group in the 2-position, an aryl or heteroaryl group in the 4-position and an alkyl group in the 5-position are effective in controlling aphids, insects and mites.
