WebFeb 4, 2016 · That way, you never break the bond between the core and the substituent and the chirality is preserved - it might change from R to S, because that depends on the atomic numbers of the atoms on the chiral atom (CPK rules) but … WebMar 9, 2024 · The RDKit has special rules for dealing with systems like this and it doesn't always get things right. This is an example where it's not getting it right. You can remove the chiral markings from an atom manually by calling SetChiralTag () on the atom. Here's an example of doing that for your molecule:

WebSep 1, 2024 · RDKit Version: 2024.09.1; Platform: Pop OS 18.04 LTS (Ubuntu 18.04 LTS) When removing and adding the same bond the chirality sometimes changes if the new bond has a higher idx than before. I am not a chemist but from my understand rdkit is using the order of the bonds to determine order in which different R groups added to the chiral center.
