User: I want to create a molecule SMILES.
Assistant: This sounds very exciting. Should I consider any constraints for the creation?
User: Yes, please. The molecule can be described as:
The molecule is the intermediate in the biosynthesis of vitamin B12 from uroporphyrinogen III in which three methyl groups have been introduced at positions 2, 7 and 20 of the tetrapyrrole framework. It is a conjugate acid of a precorrin-3A(7-).
Assistant: Ok, here you go, this SMILES fits this description: C/C1=C2/N=C(/C=C3\N/C(=C\c4[nH]c(c(CCC(=O)O)c4CC(=O)O)Cc4[nH]c1c(CC(=O)O)c4CCC(=O)O)[C@@H](CCC(=O)O)[C@]3(C)CC(=O)O)[C@@H](CCC(=O)O)[C@]2(C)CC(=O)O
