Oxazolidine kinetic resolution

Particularly significant is the extension to the S5mthesis of enantioenriched oxazolidin-2-thiones of the reaction of isothiocyanate 189 with aromatic aldehydes. This reaction is catalysed by Mg(C104) and the asymmetric induction is provided by a pybox ligand <05AG(E)1543>. A different approach to enantioenriched oxazolidin-2-thione was provided by a kinetic resolution of racemic substrate with an organic catalyst. Compound 192 efficiently catalysed the methanolysis of iV-acyl oxazolidinethiones 191 and afforded an efficient kinetic resolution of 191 with an s-factor up to 32 <05JA13502>. [Pg.305]
