Stereochemical Studies of Chiral Acyclic Nitroxides Coupling with a Prochiral Radical.

Abstract A series of acyclic chiral nitroxides bearing a hydrogen atom on the carbon adjacent to the nitroxide nitrogen was investigated for stereoselectivity in a coupling reaction with the prochiral radical 1‐phenethyl. In one case, an x‐ray structure of the major diastereomer was obtained, which corroborates a model for predicting the stereoselectivity.
