The combination of 2-NsNCl2/2-NsNHNa as the nitrogen and chlorine sources and copper(I) triflate as the catalyst enables a regio- and stereoselective aminochlorination of cinnamic esters to provide anti-alkyl 3-chloro-2-(o-nitrobenzenesulfonamido)-3-phenylpropionate derivatives with good yields and stereoselectivity.
