Rapid pyramidal inversion is a well-documented characteristic of amines and related compounds, presenting a significant barrier to isolating chiral nitrogen centers unless specifically restricted.

The analysis

Multiple retrieved papers explicitly confirm that rapid pyramidal inversion occurs in amines and is responsible for the historical difficulty in isolating nitrogen-stereogenic compounds without structural constraints.

Paper [2] notes that enantioselective approaches to acyclic N-stereogenic amines are hindered by their rapid pyramidal nitrogen inversion.
