スポンサーリンク
概要
- 論文の詳細を見る
Total synthesis of (-)-β-bourbonene (3) was achieved by employing the (2+2) photocycloaddition reaction of (S)-γ-pivaloyloxymethyl-β-methyl-γ-butenolide (5e) with cyclopentenone ethyleneacetal (15). The major photoadduct (16) was readily converted to the cis, anti, cis-tricyclo[5.3.0.0^<2,6>]decane system (22) in 70% yield. Further transformation provided the optically pure title compound (3).
