of neurodegeneration diseases. In this paper, we report the total synthesis of (+/-)-1, employing, as key steps, a novel desymmetrization protocol of meso-diketone to construct the core cis-bicyclo[3.3.0]octyl system of 1 (3 --> 2) and a radical cyclization to install the highly congested C9-quaternary carbon (16 --> 17).
Merrilactone A (1) 已被证明具有神经营养活性,因此有望在神经退行性疾病的治疗中具有治疗潜力。在本文中,我们报告了 (+/-)-1 的全合成,作为关键步骤,采用了一种新型的内消旋二酮去对称化方案来构建 1 (3 --> 2) 和自由基环化以安装高度拥挤的 C9-季碳 (16 --> 17)。
