A formal total synthesis of (−)-brevisamide, a monocyclic ether amide with architecturally unique structural features, has been achieved. The tetrahydropyran core part of the target was synthesized by the aldol reaction followed by ring-closing metathesis using the Grubbs second generation catalyst. After the stereochemistry at the carbon center bearing the hydroxy group was adjusted, the carbon–carbon
已经实现了(-)-灯盏花酰胺的正式全合成,这是一种具有结构上独特的结构特征的单环醚酰胺。靶的四氢吡喃核心部分是通过醛醇缩合反应,随后使用格鲁布斯第二代催化剂进行闭环复分解合成的。调整了带有羟基的碳中心的立体化学后,碳-碳双键通过催化氢化被立体选择性地还原。最后,在引入氨基之后进行乙酰化,这提供了所需的高级中间体。
