  To develop natural-product-based pesticidal agents, a series of monosaccharide-related ester derivatives (17a–q and 18a–f), glucose (xylose)-piperic acid/piperic acid-like conjugates, were synthesized. Three-dimensional structures of compounds 17b, 17g, 17h, and 17n were unambiguously determined by single-crystal X-ray diffraction. Especially compounds 18e and 18f exhibited the most potent insecticidal

  Direct aerobic α,β-dehydrogenation of γ,δ-unsaturated amides and acids using a simple iridium/copper relay catalysis system is described. We developed a new strategy that overcomes the challenging issue associated with the low α-acidity of amides and acids. Instead of α-C-H metalation, this reaction proceeds by β-C-H activation, which results in enhanced α-acidity. Conjugated dienamides and dienoic acids

  描述了使用简单的铱/铜中继催化系统对 γ,δ-不饱和酰胺和酸进行直接有氧 α,β-脱氢。我们开发了一种新策略来克服与酰胺和酸的低 α 酸度相关的挑战性问题。该反应不是 α-CH 金属化，而是通过 β-CH 活化进行，从而导致 α-酸性增强。共轭二酰胺和二烯酸通过该反应以优异的产率合成，该反应使用简单的反应方案。机理实验表明催化剂静止状态机制，其中 α-CH 和 β-CH 裂解都被加速。
