The modified Mg : Al (3 : 1) hydrotalcite has been found to be an efficient catalyst in the conversion of carbamates into oxazolidin-2-ones under mild reaction conditions. A wide variety of oxazolidin-2-ones were obtained with excellent chemical yield.

2-Phenyloxazolin-5-one (2) acts as a 'derivatizing agent' in the lipase catalyzed kinetic resolution of N-ethoxycarbonyl-2-amino-1-butanol (1) inorganic solvents. Unique structural alteration possible due to condensation with 2 gives enough scope for the separation of product and substrate isomers without using column chromatography.
