  Use of Conjugated Dienones in Cyclialkylations:  Total Syntheses of Arucadiol, 1,2-Didehydromiltirone, (±)-Hinokione, (±)-Nimbidiol, Sageone, and Miltirone

  摘要：

  Functionalized hydrophenanthrenes can be prepared using a cyclialkylation-based strategy. These annulations are highly dependent on the directing effects of the arene substitutents and on conformational considerations. The utility of this methodology was featured in the syntheses of six diterpenoids.

  methodology for synthesizing 2,3-benzodiazepines and their analogues by means of phosphate-assisted acylation reaction of 1-arylpropan-2-ones with a carboxylic acid followed by hydrazine cyclization in a one-pot two-step manner. An unprotected amino group is tolerated in this reaction. This method provides a direct access to 2,3-benzodiazepines containing aromatic 7,8-dimethoxy and 1-p-aminophenyl groups,

  在这里，我们报告了通过1-芳基丙烷-2-酮与羧酸的磷酸盐辅助酰化反应，然后以一锅两步的方式将肼环合，合成2，3-苯并二氮杂及其类似物的新方法。在该反应中容许未保护的氨基。该方法可直接获得含有芳香族7,8-二甲氧基和1-对氨基苯基基团的2,3-苯并二氮杂卓，这通常被认为对生物活性很重要。在1-芳基丙烷-2-酮的苯环上存在3，4-二甲氧基或3-甲氧基取代对于酰化反应中的高区域选择性很重要。

  日期：2008.4

  benzaldehydes and subsequent α,β-epoxy rearrangement is reported. The process developed is both amenable to large scale and parallel synthesis. While electron-poor benzaldehydes gave mixtures of aryl ketones and 2-substituted aryl ketones in mediocre to low yields, electron-rich benzaldehydes were found to react in high yields with complete regioselectivity to form 2-substituted aryl ketones.
