Abstract

The synthesis of enantiomerically pure iodoarenes and their application to the α-oxysulfonylation of propiophenone, and the lactonization of 5-oxo-5-phenylpentanoic acid using MCPBA as stoichiometric oxidant are reported to give useful synthetic intermediates in good yields and moderate enantioselectivities.

Key words

hypervalent iodine reagents - organocatalysis - oxidation - stereoselective synthesis
