The facile synthesis of 4 and (±)-6 was carried out via a Diels-Alder type [2+4] cycloaddition reaction of oligomeric dien 8 with styrene or t-stilbene, respectively, as a dienophile by a thermal reaction and/or photoreaction. (±)-6 crystallized as a racemic compound composed of (2R,3R) and (2S,3S) enantiomers.
