  Further Studies of the Daphniphyllum Alkaloid Polycyclization Cascade

  摘要：

  The scope of the 2-azadiene intramolecular Diels-Alder cyclization, previously employed for synthesis of the Daphniphyllum alkaloids, has been further investigated. Through a series of 1,5-diol cyclization precursors the substitution pattern of both the dienophile and the 8-azadiene were examined. From these studies it was shown that the cascade reaction is tolerant toward a variety of alkyl-substituted dienophiles. However, it was also demonstrated that this reaction is very sensitive to the substitution pattern of the 2-azadiene. Alterations made to the structure of the 2-azadiene cause either competing side reactions or complete failure of the reaction cascade.

• Synthetic studies toward longeracemine: The intramolecular [4+2] cycloaddition of 3H-pyrroles

  日期：2018.8

  Model studies to develop a tetracyclization approach mimicking the proposed biosynthesis of the secodaphnane-type alkaloid longeracemine are described. These studies have culminated in the successful implementation of a 3H-pyrrole [4+2] cycloaddition that delivers a longeracemine-like azabicycle containing three contiguous quaternary stereocenters.

  描述了开发四环化方法的模型研究，该方法模拟拟议中的苏打法烷型生物碱长乙胺的生物合成。这些研究最终成功地实现了3 H-吡咯[4 + 2]环加成反应，该环加成反应产生了一个包含三个连续的四级立体中心的类似长乙胺的氮杂双环。
