SMILES without property info

[rajathsalegame]

Is there an easy way to convert a mol that has stored properties to SMILES without the properties getting encoded into the SMILES? I need the mol to retain properties, because for some strange reason, adding atom map numbers as a property to the mol results in reversed chirality when I write the SMILES. That bug is referenced here: #3835

I've commented on #3835 itself, but that's not a bug.

If you want to output a SMILES that doesn't include atom map numbers, you can just remove the atom map numbers from the molecule by setting them to zero:

>>> m = Chem.MolFromSmiles('[CH3:1][OH:2]')
>>> Chem.MolToSmiles(m)
'[CH3:1][OH:2]'
>>> for atom in m.GetAtoms():
...     atom.SetAtomMapNum(0)
... 
>>> Chem.MolToSmiles(m)
'CO'
