A range of amines was reacted with norcantharidin (2) to provide the corresponding norcantharimides (9-43). Treatment of norcantharidin with allylamine afforded the corresponding allyl-norcantharimide (20) which was amenable to epoxidation (mCPBA, 22) and

Full details of the enantioselective reduction of cyclic meso-imides catalysed by an enantiopure oxazaborolidine derived from (S)-α,α-diphenylprolinol are reported. Treatment of the imides with borane in the presence of the catalyst led to a mixture of cis- and trans-hydroxylactams and, after subsequent ethanolysis, to the corresponding diastereomerically pure trans-ethoxylactams. The enantiomeric excesses were shown to be 68-94% by HPLC-determination. One example, in which the ethoxylactam was converted into the benzenesulfonyllactam, could be crystallized to >99% enantiomeric purity.
