A Convenient Synthesis ofN‐Boc‐Protected α‐Aminonitriles from α‐Amidosulfones
摘要:
Synthesis of N-Boc-protected alpha-aminonitriles starting from N-Boc-protected alpha-aminosulfones is described. Treatment of the sulfone with two equivalents of potassium cyanide in 2-propanol or dichloromethane-H2O under phase transfer condition affords crystalline N-Boc-protected alpha-aminonitriles in good yield. Hydrolysis of the aminonitriles provides a convenient access to racemic a-amino acids.

Processes for the efficient production of chiral amino nitrites are disclosed. Generally, the processes include the esterification of the alcohol of a amino protected alcohol followed by nucleophilic substitution of the ester with a cyano group. In an exemplary embodiment the chiral amino nitrile produced is (R)-3-aminopentanenitrile.
