Hi Lauren,
SMARTS doesn't have a direct way of saying an atom is non-racemic, but you
can express that idea using recursive SMARTS. For example,
In [46]: racemic =
Chem.MolFromSmiles('c12c1cncc2NC(=O)C(CCO2)c1cc(Cl)ccc12')
In [47]: chiral1 = Chem.MolFromSmiles('c12c1cncc2NC(=O)[C@H
Hi,
I would like to perform a substructure search in which a racemic chiral SMARTS
finds only racemic compounds and not those that have specified stereochemistry,
e.g these compounds from the COVID moonshot project:
Does anyone know if there’s a way to specify this distinction in an rdkit
