    • During our investigation, Jacobsen et al. reported asymmetric catalytic addition to imines with HCN or ketene silyl acetals. Very recently, Schreiner et al. also revealed urea catalyzed 1,3-dipolar cycloaddition with nitrone but the effect was small. See: (a) Vachal, P.; Jacobsen, E. N. J. Am. Chem.
