Enantioselective vinylation of aldehydes via direct catalytic asymmetric Grignard reaction of aldehdyes and the vinyl Grinard reagent is a long‐standing challenge. This work demonstrated that the magnesium (S)‐3,3′‐dimethyl BINOLate enantioselectivelycatalyze the direct vinylation of aldehydes with the deactivated vinylmagnesium bromide by bis(2‐[N,N′‐dimethylamino]ethyl) ether (BDMAEE) in the addition
A colorimetric high throughput screening method was developed based on a dual-enzyme cascade and used for the directed evolution of cytochrome P450 hydroxylase activity.
