Abstract

A range of structurally and functionally varied enantiopure cyclic and bicyclic guanidines has been prepared and evaluated in the enantioselective epoxidation of 3-tertbutoxycarbonylamino-4,4-dimethoxycyclohexa-2,5-dien- 1-one 1 using tert-butylhydroperoxide. Encouraging enantiomeric excesses were observed (up to 60%). Low enantiomeric excesses were also observed with 2-methylnaphthoquinone and trans-chalcone.
