On the structure and chiroptical properties of (S)-4-isopropyl-oxazolidin-2-one

The specific rotation of (S)-4-isopropyl-oxazolidin-2-one is extremely solvent dependent. In chloroform it is dextrorotatory {[α]D26 = + 15.5 (c 5.2, CHCl3)}, whereas in ethanol it is levorotatory {[α]D26 = - 16.1 (c 5.2, EtOH)}.

Resolution of pentafluorophenyl esters using oxazolidin-2-ones

A series of structurally related racemic pentafluorophenyl active esters were resolved using an equimolar amount of (S)-4-phenyloxazolidin-2-one. The levels of diastereocontrol were found to be excellent (80-96% de) at ～40% conversion.

Resolution of pentafluorophenyl active esters using (S)-4-phenyloxazolidin- 2-thione

A series of structurally related racemic pentafluorophenyl active esters were resolved using an equimolar amount of (S)-4- phenyloxazolidin-2-thione. The levels of diastereocontrol were found to be excellent (>86% de at -30% conversion).
