摘要
A multidimensional screening of catalysts and additives led to the discovery of improved conditions for the diastereoselective reductive amination which produces enalapril. Additives acetic acid and potassium fluoride, which in isolation are detrimental, work together to improve the SSS : RSS selectivity with Ra-Ni in ethanol to 17 : 1 from 11 : 1.
