Two Oxazolidinone Derivatives

The structures of two substituted oxazolidinones, namely, 4-hydroxymethyl-4-methyloxazolidin-2-one [C₅H₉NO₃, (1)] and 4-ethyl-4-hydroxymethyloxazolidin-2-one [C₆H₁₁NO₃, (2)], are reported. Bond distances in the two structures are almost identical. The oxazolidinone rings both adopt envelope conformations; the fold in (1) is significantly larger than that in (2). There is no intramolecular hydrogen bonding in either structure and the intermolecular hydrogen-bonding schemes are very similar.
