(+)-Ryanodine和(+)-ryanodol是复杂的二萜类化合物,其调节ryanodine受体的细胞内Ca 2+释放,ryanodine受体是骨骼肌和心肌兴奋-收缩偶联和突触传递的关键离子通道。这些二萜类化合物的化学衍生化已经证明,某些外围结构修饰可以改变兰尼碱受体亚型之间的结合亲和力和选择性。在这里,我们报告了一个简短的化学合成(+)-ryanodol的过程中,只有15个步骤,从市售的萜烯(S)-胡薄荷酮。合成的效率来自于使用Pauson-Khand反应来快速构建碳框架,以及在一步中安装三个氧原子的显着SeO 2介导的氧化。这项工作突出了如何战略C-O键的建设可以简化多羟基化萜烯的合成,最大限度地减少保护基团和氧化还原调节。
(+)-Ryanodine and (+)-ryanodol are complex diterpenoids that modulate intracellular Ca2+ release at ryanodine receptors, ion channels critical for skeletal and cardiac muscle excitation–contraction coupling and synaptic transmission. Chemical derivatization of these diterpenoids has demonstrated that certain peripheral structural modifications can alter binding affinity and selectivity among ryanodine receptor isoforms. Here we report a short chemical synthesis of (+)-ryanodol that proceeds in only 15 steps from the commercially available terpene (S)-pulegone. The efficiency of the synthesis derives from the use of a Pauson-Khand reaction to rapidly build the carbon framework, and a remarkable SeO2-mediated oxidation to install three oxygen atoms in single step. This work highlights how strategic C–O bond constructions can streamline the synthesis of poly-hydroxylated terpenes by minimizing protecting group and redox adjustments.
