WebThe algorithm works as follows: Use SMARTS to find the strongest protonated acid and the weakest ionized acid. If the ionized acid is weaker than the protonated acid, swap proton and repeat. Recalculate stereochemistry ¶ Use built-in RDKit functionality to force a clean recalculation of stereochemistry WebThis uses a text file as SMARTS input. I cannot seem to replicate the SMARTS format used here. For this, I plan to use the Rdkit One Component Reaction node which uses a set of compounds to carry out the reaction on as input and a SMARTS string that defines the reaction. My issue is the generation of a working SMARTS string describing the reaction.

RDKit does generate an explicit single bond, as 'c-c', for single bonds which connect two aromatic atoms. This is the right thing to do, and it means that I can work around this problem syntactically by post-processing the SMILES to insert the ':'s where needed.
