- 論文の詳細を見る
On the assumption that non-activated C-H bond should be functionalized by the photolysis of some nitrones, the nitrone [24] derived from Enmein [1] in 14 steps was photodecomposed under various conditions, and the expected products [25 and 26] were obtained in a favorable yield. The structure of the compound [25] was determined unequivocally, and the possible mechanisms (d and e) (Fig. 4) were presumed. The compound [25] was then converted into gibberellin A_<15> in 6 steps. The route of [41]→[43]+[44] seems to be interesting, suggesting the biogenesis of gibberellin from kaurene.
