What's Happening?
A research team has successfully developed a new method for asymmetric cyanoesterification of vinylarenes using electrochemical copper catalysis. This innovative approach involves the use of iron phthalocyanine and Cu(OTf)2 in combination with a bisoxazoline ligand, achieving promising yields and excellent enantioselectivity. The method was optimized to work without iron catalysis, resulting in an isolated yield of 80% with 92% enantiomeric excess. The study explored various reaction conditions, including the copper-to-ligand ratio and the use of different cathodes, to maximize efficiency. The protocol was tested on a range of vinylarenes, yielding chiral β-cyano esters with diverse functional groups. The method also demonstrated compatibility with electron-rich and electron-deficient heterocycles, and was successfully scaled up for practical applications.
