J. Mcnulty et al., A new structural motif for rigid C-2-symmetrical propeller-shaped 1,2-diamines employing double aromatic pi-stacking, CHEM COMMUN, (22), 2001, pp. 2384-2385
Utilization of double aromatic pi -stacking interactions on a 2,3-diaminobu
tane framework provides a new motif for structurally rigid C-2-symmetrical
propeller-shaped chiral 1,2-diamines.
