2 OXAZOLIDINONE DERIVATIVES

The structures of two substituted oxazolidinones, namely, 4-hydroxymet hyl-4-methyloxazolidin-2-one [C5H9No3, (1)] and 4-ethyl-4-hydroxymethy loxazolidin-2-one [C6H11NO3, (2)], are reported. Bond distances in the two structures are almost identical. The oxazolidinone rings both ado pt envelope conformations; the fold in (1) is significantly larger tha n that in (2). There is no intramolecular hydrogen bonding in either s tructure and the intermolecular hydrogen-bonding schemes are very simi lar.
