advantages of our methodology include an increased synthesis speed, very mild conditions giving access to hitherto unknown or highly reactive classes of isocyanides, rapid access to large numbers of functionalized isocyanides, increased yields, high purity, proven scalability over 5 orders of magnitude, increased safety and less reaction waste resulting in a highly reduced environmental footprint. For example

The invention relates to a group of hydronopol derivatives which are agonists on human ORL1 (nociceptin) receptors. The invention also relates to the preparation of these compounds, to pharmaceutical compositions containing a pharmacologically active amount of at least one of these novel hydronopol derivatives as an active ingredient, as well as to the use of these pharmaceutical compositions for the treatment of disorders in which ORL1 receptors are involved.
The invention relates to compounds of the general formula (1)
wherein the symbols have the meanings as given in the description.
Heteroarylpiperidine and -piperazine derivatives of the formula (I),
in which the symbols have the meanings given in the description and agrochemically active salts thereof and their use for controlling phytopathogenic harmful fungi and also processes for preparing compounds of the formula (I).
The first [1+1+1] cycloaddition reaction has been achieved on the Ag(111) surface to afford the aza[3]radialenes. The chlorine substituents in the isocyanides ensured the selectivity and orientational order of the products via the steric hindrance-directed molecular assembly.
6‐diol and the relevant Co complex (Fe3O4@Phendiol@Co) synthesized as a nano‐magnetic heterogeneous catalyst to be used for the N‐formylation of variousamines at room temperature under solvent‐free conditions. Also, in order to find the better concept of the catalyst role, the N‐formylation reaction was carried out by the use of ultrasound irradiation in the absence of the Co nano‐catalyst and the results
用1,10-菲咯啉-5,6-二醇修饰Fe 3 O 4磁性纳米颗粒(Fe 3 O 4 MNPs),并合成相关的Co络合物(Fe 3 O 4 @ Phendiol @ Co),作为纳米磁性异质体室温下在无溶剂条件下用于各种胺的N甲酰化的催化剂。此外,为了找到催化剂作用下,的更好的概念ñ在不存在Co纳米催化剂的情况下,通过超声辐射进行甲酰化反应,并对结果进行比较。该催化剂采用不同的方法进行表征,例如元素分析(CHN),ICP,FT-IR,XRD,EDX,SEM,TEM,TG-DTA,VSM和XPS。此外,通过2,2-二苯基-1-吡啶甲基肼基(DPPH)自由基清除和圆盘扩散方法体外筛选了Fe 3 O 4 @ Phendiol @ Co纳米催化剂及其酚配体的抗氧化剂和抗菌活性。。结果表明,与标准品相比,它们具有很强的抗氧化活性(IC 50; 0.182±0.006 mg / ml)和良好的抗菌潜力。
