    • 1H NMR showed a trans, trans, cis coupling constant of ddd (J=12.4, 8.4, 4.4 Hz) pattern. From this fact, it was concluded that product (-)-12 was generated from the cycloadduct 8a. In addition, the other intermediates shown in Schemes 2 and 3 also showed that the coupling constant of H at C3 matched with the trans, trans, cis type. In case of (+)-9, although its stereochemistry was not clear at first, the same compound (-)-12 with the same physical data after several reaction steps was obtained.{A figure is presented}
