2-Amino-2,3-dimethylbutanamide

open access: yesActa Crystallographica Section E, 2010
The title compound, C6H14N2O, was synthesized by the reaction between 2-amino-2,3-dimethylbutanonitrile and oil of vitriol (sulfuric acid). A racemic mixture of L- and R-2-amino-2,3-dimethylbutanamide was characterized crystallographically.

Stability of racemic and chiral steady states in open and closed chemical systems

open access: yes, 2008
The stability properties of models of spontaneous mirror symmetry breaking in chemistry are characterized algebraically. The models considered here all derive either from the Frank model or from autocatalysis with limited enantioselectivity.
