The stereochemistry of the cobalt(II) chloride catalysed opening of cinnamoyl epoxides with N-substituted anilines is controlled by the para substituent of the aromatic ring attached to nitrogen atom. Thus the secondary amine having a para methoxy group cleaves the epoxide to afford the corresponding anti amino alcohol as the major product whereas amines containing para chloro, bromo, methyl or hydrogen
