(tert-Butoxycarbonylamino)acetonitrile

The title compound, C₇H₁₂N₂O₂, is a useful intermediate for the synthesis of peptidic nucleic acids (PNAs) containing a backbone composed of repeating (2-aminoethyl)glycine units. Conjugation within the urethane system is facilitated by near planarity about both C-O and C-N bonds. There is a synperiplanar relationship between the O11 atom of the carbonyl group and the tertiary C7 atom, along with an antiperiplanar relationship between the C5 atom and the C10 methyl group.
