rhynchophylline, a highly enantioselective and efficient organocatalyzed synthesis method was developed that gives access to the tetracyclic secoyohimbane scaffold, embodying a quaternary and three tertiary stereogenic centers in a one-pot multistep reaction sequence. Investigation of a collection of the secoyohimbanes in primary rat hippocampal neurons and embryonal stem cell-derived motor neurons led
具有神经调节活性的天然产物及其潜在的结构支架可能会激发新型神经营养化合物的合成。螺环七高辛烷生物碱茶碱是中药用于治疗中枢神经系统疾病的钩藤属植物提取物的主要成分。基于乙酰胆碱的结构,开发了一种高度对映体选择性和高效的有机催化合成方法,该方法可访问四环七代辛烷骨架,在一个多步反应序列中包含一个四级和三个三级立体异构中心。
