User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a 3-pyranone with a 4,5-double bond carrying a hydroxy group at position 4 and a hydroxymethyl group at position 6. It is a deoxyketohexose, an anhydrohexose and a member of 3-pyrones. It is a conjugate acid of an ascopyrone M(1-).
Assistant: This is a molecule that fits your description: O=C1CO[C@H](CO)C=C1O
