Application

sBOX(tBu) is a serine-derived chiral bisoxazoline ligand. The additional coordinating functionality provided by the esters enables new reactivity compared to traditional BOX ligands. sBOX(iPr) has been shown to be an optimal ligand for the electrocatalytic cyanophosphorylation as well as hydrocyanation of vinylarenes.

Product can be used with our Synlectro electrochemistry platform (ESYNTH001)

In contrast to the rapid growth of synthetic electrochemistry in recent years, enantioselective catalytic methods powered by electricity remain rare. In this work, we report the development of a highly enantioselective method for the electrochemical cyanophosphinoylation of vinylarenes. A new
