Task: Please generate a SMILES based on the text description below.
Description: The molecule is a 2-oxo monocarboxylic acid anion that is the conjugate base of (R)-3,4-dihydroxy-2-oxobutanoic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is a hydroxy monocarboxylic acid anion and a 2-oxo monocarboxylic acid anion. It is a conjugate base of a (R)-3,4-dihydroxy-2-oxobutanoic acid. It is an enantiomer of a (S)-3,4-dihydroxy-2-oxobutanoate.
Result: O=C([O-])C(=O)[C@H](O)CO
