Stereoselective amino alcohol synthesis via chemoselective electrocatalytic radical cross-couplings Amino alcohols are essential in pharmaceuticals, agrochemicals and other applications. Now, using a serine-derived chiral carboxylic acid, an electrocatalytic decarboxylative transformation enables efficient and ste...
The aldol reaction can also be catalyzed by acid, where it proceeds through an enol intermediate. For more on that,see here. Notes Note 1. One study measured the equilibrium constant K to be about 400 [Ref]. The equilibrium constant decreases as steric hindrance in the product increases (e...
