WebJul 31, 2016 · Nevertheless, their geometry is clearly distinguishable. For organic molecules that have 2 chiral centres, there are 2 pairs of enantiomers, R,R and S, S, and R,S, and S,R. Sometimes, S, R is equivalent to R, S. Nevertheless R,S shares a diastereomeric relationship with R,R and S,S, the enantiomers. WebMar 3, 2006 · From this equation, it is clear that enantiomer ratio is the most appropriate relationship to describe enantioselectivity. Also during the 1980s, as methods of auxiliary mediated asymmetric synthesis advanced, “ee” spawned the term “de” (diastereomeric excess). The idea was that - once a chiral auxiliary is removed, ...
