The first catalytic acylation of alcohols with a thiol ester present in Wittig reagents under neutral conditions catalyzed by the Cu(II) salt through a push-pull mechanism is reported. Furthermore, a new methodology for the one-pot lactonization of acyloins by a copper catalyst is developed. The synthetic utility of this method for the synthesis of natural products is shown.
Efficient radical oxygenation of α-lodocarboxylic acid derivatives

(equation presented) Treatment of α-iodocarboxylic acid derivatives with 2 equiv of triethylborane under oxygen atmosphere gives the corresponding α-hydroxy add derivatives This method is based on an iodine atom transfer from the ethyl radical, generated by the reaction of riethylborane and oxygen, with the α-iodocarbonyl compound. It offers several advantages over classical ionic substitution reactions: no elimanation product is observed tertiary iodides are efficiently converted to alcohos, and finally, this one-step procedure is working with substrates sensitive to nucleophiles.
