Examination of the Potential for Adaptive Chirality of the Nitrogen Chiral Center in Aza-Aspartame

Autor: Samir H. Bouayad-Gervais, William D. Lubell

Publikováno v: Molecules, Vol 18, Iss 12, Pp 14739-14746 (2013)

The potential for dynamic chirality of an azapeptide nitrogen was examined by substitution of nitrogen for the α-carbon of the aspartate residue in the sweetener S,S-aspartame. Considering that S,S- and R,S-aspartame possess sweet and bitter tastes,

Memory of Chirality in 1,4-Benzodiazepin-2-ones

Autor: DeGuzman, Joseph Christopher

Memory of chirality (MOC) is an emerging strategy in asymmetric synthesis. It has been applied to enolate chemistry, reactions involving carbocation intermediates, and to radical systems. In this strategy the chirality of an enantiopure reactant is t
