Page/Page column 10-11, (2013/02/27)
A method for producing an α-acyloxycarbonyl compound of the present invention includes performing an intermolecular reaction between a carboxylic acid and a carbonyl compound selected from the group consisting of ketones, aldehydes, and esters, which have

It′s the iodine: The intra- and intermolecular title reaction is catalyzed by an in situ generated ammonium (hypo)iodite species. Either H 2O2 or tert-butyl hydroperoxide (TBHP) can be used as an environmentally benign oxidant and a wide range of substrates react to give the corresponding α-acyloxycarbonyl compounds in good to excellent yields.

Highly enantioselective phase-transfer-catalyzed alkylation of tert-butyl 2-benzoyloxy-3-oxobutanoate was realized by the use of an N-spiro chiral quaternary ammonium salt, as a complementary approach to the asymmetric hydroxylation of α-alkyl-β-keto esters. The synthetic utility of the alkylated compounds is highlighted by the diastereoselective reduction and alkylation of the remaining ketone moiety to give various enantiomerically enriched congested 2, 3-dihydroxycarboxylic acid esters.
