Strecker Amino Acid Synthesis
The Strecker amino acid synthesis, also known simply as the Strecker synthesis, is a method for the synthesis of amino acids by the reaction of an aldehyde with cyanide in the presence of ammonia. The condensation reaction yields an α-aminonitrile, which is subsequently hydrolyzed to give the desired amino acid. The method is used for the commercial production of racemic methionine from methional. Primary and secondary amines also give N-substituted amino acids. Likewise, the usage of ketones, instead of aldehydes, gives α,α-disubstituted amino acids. Reaction mechanism In the first part of the reaction process, the carbonyl is converted to an iminium, to which a cyanide ion adds. First, the carbonyl oxygen of an aldehyde is protonated, followed by a nucleophilic attack of ammonia to the carbonyl carbon. After subsequent proton exchange, water is cleaved to form the iminium ion intermediate. A cyanide ion then attacks the iminium carbon yielding an aminonitrile. In the se ...
