背景情况:
- 丁醇3 (AM3) 是一种强效的抗真菌化合物,是从丁 (Amphidinium klebsii) 中分离出来的.
- 由于其复杂的非循环结构和有限的自然供应,确定AM3的绝对配置具有挑战性,导致多次结构修订.
- 总合成仍然是确认复杂天然产品结构的最可靠方法.
研究的目的:
- 实现第一个全合成Amphidinol 3 (AM3), 确定其修订的结构.
- 为相关的安菲丁醇化合物制定总体合成策略.
- 设计和合成一种简化,生物活性的AM3类似物,以了解其抗真菌机制.
主要方法:
- 采用了五个步骤的总合成策略,其中包括三个关键组件的融合组装.
- 使用计算分析来帮助确定结构,尽管总合成是最终的确认方法.
- 通过合成简化模拟物与截断的聚醇部分进行了结构-活性关系研究.
主要成果:
- 在五个步骤中成功完成了首次AM3的总合成,在20多年后验证了修订后的结构.
- 合成途径为制备其他安菲丁醇类产物提供了多功能平台.
- 一种简化的合成类型的AM3表现出类似的抗真菌活性,这表明较短的多链足以产生生物活性.
结论:
- 总合成无疑证实了安菲迪诺的修订结构.
- 开发的合成方法适用于更广泛的安菲丁醇化合物.
- 创建一个简化的类似物为AM3的抗真菌作用模式提供了宝贵的见解,并为开发新的抗真菌剂开辟了道路.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.

Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
