(The last is RDKit-specific becuse RDKit's canonical SMILES ends up placing branches with wildcard atoms before any other branches.) The following code automates that process.

WebSep 1, 2024 · This is the approach taken in the RDKit. Instead of using patterns to match known aromatic systems, the aromaticity perception code in the RDKit uses a set of rules. The rules are relatively straightforward. Aromaticity is a property of atoms and bonds in rings. An aromatic bond must be between aromatic atoms, but a bond between aromatic … WebJul 12, 2014 · Atom no. 7 is a neutral nitrogen and it has 4 bonds. It is possible that you could silence RDKit in some way and force it to produce some answer, but I think you should really fix the molecule. It seems that you just need to change the bond between N7 and C4 to single and change the bond between C4 and C2 to double. WebJan 24, 2024 · Explicit valence for atom # 9 N, 4, is greater than permitted. This is because of the co-ordinate bond present in the molecule which RdKit doesn't support. RdKit will treat it as a single bond which will raise the valency of both the Nitrogen atoms to 4 and hence an invalid molecule. Here's the same molecule generated from other sources: philosophical essay prompts
