User: I want to create a molecule SMILES.
Assistant: This sounds very interesting. Should it be a special one?
User: Yes, the molecule can be described as:
The molecule is the intermediate in the biosynthesis of vitamin B12 from uroporphyrinogen III in which eight methyl groups have been introduced into the tetrapyrrole framework, together with ring contraction and decarboxylation. It is a conjugate acid of a precorrin-8X(7-).
Assistant: Ok, here you go, this SMILES fits your description: CC1=C(CCC(=O)O)C2=N[C@@]1(C)CC1=N/C(=C(/C)C3=N[C@@](C)([C@@H]4N=C(C2C)[C@](C)(CCC(=O)O)[C@H]4CC(=O)O)[C@@](C)(CC(=O)O)[C@@H]3CCC(=O)O)[C@@](C)(CC(=O)O)[C@@H]1CCC(=O)O
