Dynamic kinetic resolution of rapidly racemizing biarylpyridine and isoquinoline N-oxide derivatives affords enantiomerically enriched conformationally stable products via KRED-mediated stereoselective reduction.

The highly electrophilic fluorosulfoxonium cation [Ph2S(O)F]+[B(C6F5)4)]- is shown to promote (n+2) annulation on Donor-Acceptor (D-A) strained cycles. This study highlights new reactions catalysed by highly electrophilic sulfoxonium cations and the...

The trapping of racemic polar carbometallic species with (-)-menthyl ( S)- 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.
