Synthetic studies directed towards naturally occurring γ-alkylidene bicyclic butenolide cochinolide is described in this manuscript. Hetero Pauson-Khand (PK) reaction of enantiopure 1,6-yne-aldehyde was employed as a key transformation to construct the crucial butenolide core, albeit in low yield. The precursor for hetero PK reaction was accessed through enzymatic kinetic resolution (EKR) and other
本手稿描述了针对天然存在的 γ-亚烷基双环丁烯内酯 cochinolide 的合成研究。对映体纯 1,6-炔醛的杂波森-坎德 (PK) 反应被用作构建关键的丁烯酸核心的关键转化,尽管产率较低。通过酶动力学拆分 (EKR) 和其他相关转化获得异质 PK 反应的前体。
