Nuclear Overhauser enhancement (NOE) studies on 25 were used to confirm that the stereochemistry of the double bond for the major isomer was E. Irradiation of the vinyl proton resulted in the enhancement of the N-benzyl protons of 3.3% and 1.6%. The relationship of the minor and major isomers, whether isomeric in alkene geometry or cis/trans diasteromers, was not established.
