N,S-DIMETHYL-S-PHENYLSULFOXIMINE. A REAGENT FOR THE OPTICAL RESOLUTION OF KETONES

The addition of the α-lithio derivative of (+)- or (-)-N,S-dimethyl-S-phenylsulfoximine to selected dl-ketones was carried out at -78 deg C in tetrahydrofuran followed by acid quench at that temperature to produce mixtures of diastereomeric β-hydroxysulfoximines.The optically-active diastereomers were chromatographically separated on silica gel.The purified diastereomers were thermolyzed at ca. 130 deg to produce optically-active ketones and the optically-active sulfoximine which could be recycled.

Hundred per cent optically pure bicyclic lactones and bicyclic ketones were easily obtained by complexation method with optically active 1,6-bis(2-chlorophenyl)-1,6-diphenylhexa-2,4-diyne-1,6-diol.
