J Am Chem Soc. 2018 Aug 29;140(34):10677-10681. doi: 10.1021/jacs.8b06432. Epub 2018 Aug 16.

Abstract

We report a chiral phosphoric acid catalyzed bromocyclization/regiodivergent reaction of racemic intermediates sequence, which is enabled by anchimeric oxygen borrowing. Different types of alkenes are applicable, and both enantiomers of the bromohydrin products were obtained in generally excellent yields and enantioselectivities. In addition, an example of enantioconvergent synthesis from the two isomeric products is presented.
