斯特雷克氨基酸合成（Strecker法）以发现者阿道夫·斯特雷克（Adolph Strecker）命名，是一种常用的合成氨基酸的方法。用醛（或酮）与氯化铵和氰化钾混合水溶液反应，生成α-氨基腈，再经水解，得到氨基酸。

该法起初是用氢氰酸和氨作试剂，但经Zelinski改进后，用氯化铵和氰化钾代替了氢氰酸和氨，从而避免了直接使用氰化氢或氰化铵，反应后得到同样的产物。用氯化铵时反应生成伯胺；若用伯胺或仲胺反应，生成取代的氨基酸。用酮反应时，得到α,α-二取代的氨基酸。

一般Strecker合成得到外消旋氨基酸，但最近有人利用不对称手性辅助剂或催化剂，用这个反应成功合成了手性氨基酸。

The Strecker amino acid synthesis, also known simply as the Strecker synthesis, was devised by German chemist Adolph Strecker, and is a term used for a series of chemical reactions that synthesize an amino acid from an aldehyde or ketone. The aldehyde is condensed with ammonium chloride in the presence of potassium cyanide to form an α-aminonitrile, which is subsequently hydrolyzed to give the desired amino acid. In the original Strecker reaction acetaldehyde, ammonia, and hydrogen cyanide combined to form after hydrolysis alanine.
