In an aqueous medium, this metal-free and benign strategy enables direct installation
of C–N and C–X bonds into olefins using the organic Lewis acid, PhIO. The surfactant-mediated
vicinal difunctionalization enables the synthesis of N-tosyl-1,2-bromoamines and 1,2-bromoazides with good regio- and stereoselectivity.
This strategy provides a straightforward route to sugar-based chiral and functionally
diverse synthons that hold great promise for applications in pharmaceutical chemistry.
