Diastereoselective synthesis of enantiomerically pure 3-organosulfonyl-2-(2-oxocycloalkyl)-1,3-oxazolidines from 2-formylcycloalkanones and β-aminoalkanols

The title compounds (3-arylsulfonyl- or 3-mesyl-2-(2-oxocycloalkyl)-1,3-oxazolidines) belonging to two different diastereomeric series, are prepared selectively by variation of the condensation conditions. By this, the chiral information of the 2-amino-1-

Arylsulfonyloxazolidine

The geometric parameters of the title compound, (2S)-2-[(2R,4S)-4-phenyl-3-tosyl-1,3-oxazolidin-2-yl] cyclo-pentanone, C21H23NO4S, are in good agreement with other arylsulfonyl-oxazolidines. While the oxazolidine ring displays an envelope conformation, the cyclopentanone ring has a twist conformation.
