Abstract
The trapping of racemic polar carbometallic species with (-)-menthyl ( SS)- p-toluenesulfinate (Andersen's reagent) typically proceeds with a very low level of resolution. In this paper, we describe a strategy that allows access to highly atropo-enriched and functionalizable biphenyls by means of Andersen's reagent under kinetic resolution conditions. In particular, useful enantiopure 2-iodobiphenyls could be obtained and were employed in a challenging hypervalent iodine-catalyzed oxidation reaction.
