Tanabalin (1), an insect antifeedant, was synthesized in optically active form employing a known δ-lactone (F) as the only source of chirality. The key step is a tandem intermolecular alkylation-intramolecular Robinson annelation to construct the trans-octalin skeleton.
用已知的δ-内酯(F)作为手性的唯一来源,以光学活性形式合成了Tanaabalin(1),一种昆虫拒食剂。关键步骤是串联分子间烷基化-分子内鲁宾逊脱核法,以构建反式-八氢
萘骨架。
