Pori, M.; Galletti, P.; Soldati, R.; Giacomini, D. Asymmetric strecker reaction with chiral amines: A catalyst-free protocol using acetone cyanohydrin in water. European Journal of Organic Chemistry 2013, 9, 168
Acetone cyanohydrin is manufactured by the direct reaction of hydrogen cyanide with acetone, catalyzed by base, generally in a continuous process. Production Methods Acetone cyanohydrin is formed by adding acetone to sodium or potassium cyanide in water and treating with H2S04 or by reaction of ac...
The reaction of α,β-unsaturated aldehydes with cyanohydrins in the presence of tertiary amines, leading to esters of cyanohydrins, proceeds through the formation of the cyanohydrin of an α,β-unsaturated aldehyde, followed by intramolecular prototropic 1,3-shift (75-80%), the formation of a...
