Syntheses and Biological Activities of Octahydro-1H-cyclopenta[d]pyrimidine Derivatives
摘要:
Various nitromethylene derivatives were synthesized regioselectively. Compounds 8a-f were obtained by the reaction of 1-((5-chloropyridin-2-yl)methyl)-2-(nitromethylene)-octahydro-1H-cyclopenta[d]pyrimidine (3) with primary amines and formaldehyde. The synthesized compounds were identified by H-1 NMR, HRMS (EI), and IR, and preliminary bioassays indicated that most of them showed moderate insecticidal activities against Aphis craccivora. The relationship between hydrophobicity and biological activity was also discussed.

Disclosed is an advancement in provoked chemical cleavage. Thereby the invention provides the use of a diene as a chemically cleavable group attached to a Construct, and the use of a dienophile to provoke the release of the Construct by allowing the diene to react with a dienophile capable of undergoing an inverse electron demand Diels Alder reaction with the diene. The invention includes a kit for releasing a Construct CA bound to a Trigger TR, the kit comprising a tetrazine and a dienophile, wherein the Trigger is the tetrazine. The invention also includes the use of the formation of a pyridazine by reacting a tetrazine comprising a Construct CA bound thereto and a dienophile, as a chemical tool for the release, in a chemical, biological or physiological environment, of said Construct.

pentanecarbonitrile, 1, and the respective carboxamides, 3, and acids, 4, have been prepared. Acidcyclization of both nitriles, faster with the cis isomer, gave the more stable cis-2-thiooxo-cyclopenta(d)pyrimidin-4-one, 7. In base cis-1 formed the cis 4-imino-2-thiooxopyrimidine 2 which in aqueous alkali broke down via 3 to the acid 4; while in the presence of 66% acetonitrile 2 rearranged to the
已经制备了 2-(3-苯基硫脲基) 环戊烷甲腈 1 和相应的甲酰胺 3 和酸 4 的顺式和反式异构体。两个腈的酸环化,顺式异构体更快,得到更稳定的 cis-2-thiooxo-cyclopenta(d)pyrimidin-4-one, 7. 在碱基 cis-1 中形成顺式 4-imino-2-thiooxopyrimidine 2在碱水溶液中经3分解成酸4;而在 66% 乙腈的存在下,2 重排为 4-苯基亚氨基嘧啶 5,得到作为最终产物的硫脲酸 6 不携带苯基。亚氨基和苯基亚氨基衍生物 2 和 5 的 1 H NMR 数据表明,在环戊烷环中具有 1-N 假轴构象的 A 构象存在强烈偏差。在 DMSO-d6 中可以记录缓慢交换下亚氨基嘧啶 2 的 E 和 Z 异构体的光谱。在 CD3OD 和 CDCl3 中观察到 5 的苯基亚氨基互变异构体,其中 E 和 Z 异构体的比例为 1:1。在 DMSO-d6
