serve as readily available, stable, and inexpensive precursors of electrophilic chlorine in the organocatalytic asymmetric chlorofunctionalization of olefins. In conjunction with commercially available organocatalysts, they can be utilized in the asymmetric chlorocyclization of unsaturated amides to yield products with unprecedented levels of stereoselectivity even at ambient temperatures and high concentrations
