  Target-oriented synthesis: miscellaneous synthetic routes to access 1,4-enediones through the coupling of 1,3-dicarbonyl compounds with multiform substrates

  摘要：

  Target-oriented synthetic protocol was presented for the synthesis of 1,4-enediones. The approach can efficiently construct 1,4-enediones through different reaction pathways from multiform substrates alpha-halo aromatic ketones, 2-hydroxy-aromatic ketones and methyl carbinols. In this reaction, CuI was found to be the most efficient catalyst. Multiform substrates were also found to perform well to afford the products in a one-pot fashion. (C) 2013 Elsevier Ltd.

  A simple, efficient, mild, and regioselective method for oxyiodination of carbonyl compounds has been reported by using NH4I as the source of iodine and Oxone® as an oxidant. Various carbonyl compounds such as aralkyl ketones, aliphatic ketones (acyclic and cyclic), and β-keto esters proceeded to the respective α-monoiodinated products in moderate to excellent yields. Unsymmetrical aliphatic ketones

  The 13 NMR singles for some 4‐substituted phenacylchlorides and iodides were assigned. The carbonyl carbons exhibit upfield shifts compared with those of the corresponding 4‐substituted acetophenones; in the chlorinated derivatives a downfield shift is observed for the α‐methylene carbons, while a reverse effect occurs in the iodinated compounds. The chemical shifts of the aromatic ring carbons are

  指定了一些 4 取代苯甲酰氯和碘化物的 13 NMR 单峰。与相应的 4-取代苯乙酮相比，羰基碳表现出高场位移；在氯化衍生物中观察到α-亚甲基碳的低场位移，而在碘化化合物中发生相反的作用。芳环碳的化学位移与使用取代基化学位移计算的那些非常一致。

  halomethylketone moiety to reversible inhibitors turned them into irreversible inhibitors with IC50 values in the nanomolar range. Overall, the results point out that these compounds might be useful pharmacological tools to explore physiological and pathological processes related to signaling pathways regulated by GSK-3 opening new avenues for the discovery of novel GSK-3 inhibitors.

  开发针对中枢神经系统（CNS）疾病的激酶靶向疗法是一项巨大的挑战。糖原合酶激酶3（GSK-3）在严重的中枢神经系统未满足疾病中具有巨大潜力，它是针对不同疾病的临床试验中的抑制剂之一。根据我们基于GSK-3结合位点残基Cys199的增强反应性的假设，我们在这里检查苯基卤代甲基酮作为不可逆抑制剂的适用性。我们的数据证实卤代甲基酮单元对于抑制活性是必不可少的。此外，在可逆抑制剂中添加卤代甲基酮部分可将其转变为具有IC 50的不可逆抑制剂值在纳摩尔范围内。总体而言，结果指出这些化合物可能是探索与GSK-3调节的信号通路相关的生理和病理过程的有用药理工具，为发现新型GSK-3抑制剂开辟了新途径。

  The hydration of haloalkynes to give α-halomethyl ketones was achieved based on a combination of a Cu(OAc)2 catalyst and a TFA (trifluoroacetic acid) promoter. This is the first synthesis of chloro/bromo/iodo methyl ketones through a hydration reaction catalyzed by a recyclable catalytic system. The catalytic system has a wide substrate scope and excellent chemoselectivity, and the procedure can also
