A range of structurally and functionally varied enantiopure cyclic and bicyclic guanidines has been prepared and evaluated in the enantioselective epoxidation of 3-tert-butoxycarbonylamino-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.

Abstract A mild and efficient procedure is described for the removal of the tert-butoxycarbonyl (BOC) group using borontrifluorideetherate and molecular sieves in dichloromethane at room temperature. The scope of this procedure is explored for the deprotection of a variety of amines including amino acid derivatives.

Efficient approaches to the central amino-epoxycyclohexenone core of the manumycin family of antibiotics are described. The use of this methodology to prepare the antitumourantibiotic LL-C10037α and its epimer, both in racemic form, and a number of analogues of manumycin, alisamycin and asukamycin, lacking the C-4 substituent, are then outlined.
