WebThe "chiral flag" is a feature that was used in MDL v2000 mol files, but was superseded by Enhanced Stereo Groups, which are much more flexible, in the v3000 format. It would be useful to have some infrastructure that allows us to "translate" the stereochemistry read from a v2000 mol block into Enhanced Stereo Groups. If my understanding of the ...
