- 論文の詳細を見る
The synthesis of (±)-cyclocymopol (1) is described. Brominative cyclization with 2,4,4,6-tetrabromocyclohexadienone of cymopol bismethoxymethyl ether (7), which was obtained by monogeranylation of 2,5-dibromohydroquinone bismethoxymethyl ether (5), resulted in the formation of an undesired tricyclic compound 9. In contrast, an analogous reaction of cymopol dimethyl ether (6) provided the requisite cyclocymopol dimethyl ether (4). A two-step reaction of 4 involving oxidative demethylation with ceric ammonium nitrate or silver dipicolinate and reduction with sodium hydrosulfite gave rise to (±)-cyclocymopol (1).
