Abstract
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.
