preparation of β‐aminonitriles. We present a highly efficient organocatalytic methodology for the stereoselective synthesis of β‐aminonitriles, in which the key to success is the use of ureidopeptide‐basedBrønstedbase catalysts in combination with (arylsulfonyl)acetonitriles as synthetic equivalents of the acetonitrile anion. The method gives access to a variety of β‐aminonitriles with good yields
