  Synthesis of N-(3,6-dihydro-1(2H)-pyridinyl)benzamides with hyperglycemic-hypoglycemic activity

  摘要：

  A group of N-(3,6-dihydro-1(2H)-pyridinyl)benzamides 7 were synthesized to determine the effect that the position and physicochemical properties of substituents attached to the heterocyclic ring have on blood glucose levels. 5-Methyl-N-(3,6-dihydro-1(2H)-pyridinyl)benzamide 7b was the most active hyperglycemic agent, elevating blood glucose 124% and 116% at 2 and 4 h, respectively, after a 100 mg/kg po dose. The most active hypoglycemic agent was the 4-acetyl analogue 7o, which was about 50% as active as chlorpropamide, lowering blood glucose 19% at 4 h after a 100 mg/kg po dose. A correlation between blood glucose levels and the partition coefficient P was not observed.

  efficient two-step synthesis of O-(2,4-dinitrophenyl)hydroxylamine is described along with a comparison of its aminating efficiency with O-mesitylenesulfonylhydroxylamine (MSH). It was used in an expedient N-amination/benzoylation procedure involving various substituted pyridines, leading to polysubstituted N-benzoyliminopyridinium ylides, and the scope of its amination power was studied.

  Extrusion of dinitrogen from enol diazoacetates with a RhII catalyst generates metal enol carbenes. Subsequent vinylogous addition of these to N‐acyliminopyridinium ylides results in an effective formal [3+3] cycloaddition to give highly substituted 1,2,3,6‐tetrahydropyridazines in up to 98 % ee and high yield.

  用 Rh II催化剂从烯醇重氮乙酸酯中挤出二氮生成金属烯醇卡宾。随后将这些化合物与N-酰基亚氨基吡啶鎓叶立德进行插烯加成，产生有效的正式 [3+3] 环加成，得到高度取代的 1,2,3,6-四氢哒嗪，  ee高达 98% ，收率高。

  We present an efficient one-pot photochemical skeletal editing protocol for the transformation of pyridines into diverse bicyclic pyrazolines and pyrazoles under mild conditions. The method requires no metals, photocatalysts, or additives and allows for the selective removal of specific carbon atoms from pyridines, allowing for unprecedented versatility. Our approach offers a convenient and efficient

  我们提出了一种有效的一锅光化学骨架编辑方案，用于在温和条件下将吡啶转化为多种双环吡唑啉和吡唑。该方法不需要金属、光催化剂或添加剂，并且可以选择性地从吡啶中去除特定的碳原子，从而实现了前所未有的多功能性。我们的方法通过替换核心吡啶骨架，为复杂药物分子的后期修饰提供了一种方便有效的方法。此外，我们已经成功地在停流和流动化学系统中扩展了该过程，展示了其对复杂转化的适用性，例如狄尔斯-阿尔德反应、氢化、[3 + 2]环加成和赫克反应。通过控制实验和 DFT 计算，我们深入了解了这种骨架编辑协议的机制基础。
