Abstract


Enantioselective reduction of N-benzyl 4-substituted glutarimides employing oxazaborolidine catalyst 3 derived from cis-1-amino-indan-2-ol occurred in moderate yield and excellent ee. This has led to the formal synthesis of two antidepressants (-)-fermoxetine 1 and (-)-paroxetine 2.

Keywords: Enantioselective, desymmetrisation, imides, glutarimides, fermoxetine, paroxetine
