1-Methyl-3-(2-(Sulfooxy)Ethyl)-1H-Imidazol-3-Ium Thiocyanate as A Novel, Green, and Efficient BrØNsted Acidic Ionic Liquid-Promoted Regioselective Thiocyanation of Aromatic and Heteroaromatic Compounds at Room Temperature
-3-ium thiocyanate ([Msei]SCN) as a Brønstedacidicionicliquid (BAIL) is described, and it is used in the highly efficient regioselective thiocyanation of aromatic and heteroaromatic compounds via a green and simple protocol. [Msei]SCN as a novel IL and thiocyanation agent, H2O2 as a mild and environmentally friendly oxidant, and H2O:ethanol(1:4) as a solvent were used. This procedure provided the

4-DHPM heterocycle was quantitatively transformed into amidoxime. Addition of aliphatic carboxylic anhydride or aromatic carboxylic acid to the amidoxime produced the expected 1,2,4-oxadiazole via the O-acylamidoxime intermediate grafted on the ILP bound 3,4-DHPM using two convergent methods. After cleavage by transesterification under mild conditions, the target compounds were obtained in good overall

N‐disubstituted thiones and selones that contain an imidazole pharmacophore. The N,N‐disubstituted thiones do not show any inhibitory activity towards LPO‐catalyzed oxidation reactions, but their corresponding N,N‐disubstituted selones exhibit inhibitory activity towards LPO‐catalyzed oxidation reactions. Substituents on the N atom of the imidazole ring appear to have a significant effect on the inhibition of LPO‐catalyzed
在本文中,我们描述了一系列包含咪唑药效基团的N,N-二取代的硫酮和色氨酸的合成和仿生活性。N,N-二取代的硫酮对LPO催化的氧化反应没有任何抑制活性,但它们相应的N,N-二取代的紫杉醇对LPO的氧化反应具有抑制作用。咪唑环N原子上的取代基似乎对LPO催化的氧化和碘化反应的抑制具有显著作用。Selones 16,17,和19,其中包含甲基,乙基,和苄基的取代基,表现出对与IC LPO催化氧化反应类似的抑制活性50个24.4,22.5,和22.5μ值中号,分别。但是,它们的活性几乎比常用的抗甲状腺药甲巯咪唑(MMI)低三倍。与此相反,selone 21,其中包含A N CH 2 CH 2 OH取代基,显示出高抑制活性,具有的IC 50值的7.2μ中号,这是类似于MMI的。这些selones对LPO催化的氧化/碘化反应的抑制活性是由于它们能够通过催化还原H 2 O 2来降低共底物(H 2 O
