The synthesis of a novel series of 3-phenylprop-2-ynylamines as selective mammalian squalene epoxidase inhibitors is described. Structure–activity relationship studies led to the discovery of compound 19, 1-[3-(3,5-dichlorophenyl)prop-2-ynyl]-3-methylpiperidine hydrochloride with an IC50 of 2.8 ± 0.6 µM against rat liver squalene epoxidase. Against 23 strains of fungal squalene epoxidase compound 19 was found to be inactive.

coordination. The magnetization of modified chitosan was done using of Fe3O4 nanoparticles. In the presence of coordinated groups of glycocyamine containing amidino and carboxylate, copper ions were immobilized on this magneticbiopolymer. This new nanocomposite (Fe3O4@CSC@AG@Cu) was characterized by FT-IR, FE-SEM, EDX, XRD, VSM, DRS and ICP analysis. After which, its catalyticactivity was examined in the three
摘要Trichloro-1,3,5-triazine试剂用于壳聚糖功能化,并作为功能化壳聚糖和糖胺之间的桥梁,形成铜配位的生物配体。改性壳聚糖的磁化是使用Fe3O4纳米粒子完成的。在含有glyco基和羧酸根的糖胺的配位基团的存在下,铜离子被固定在该磁性生物聚合物上。通过FT-IR,FE-SEM,EDX,XRD,VSM,DRS和ICP分析对这种新型纳米复合材料(Fe3O4 @ CSC @ AG @ Cu)进行了表征。此后,在脂族和芳族醛,仲环胺和苯基乙炔的三个偶联反应中,对炔丙基胺衍生物的合成进行了催化活性研究。
Catalytic Methylene Insertion between Amines and Terminal Alkynes via C–N Bond Cleavage of <i>N</i>,<i>N</i>-Dimethylacetamide: A Unique Route to Propargylic Amines
A copper-based system allows for the methylene insertion between an amine and a milder nucleophile, including a terminalalkyne counterpart, via C–N bond cleavage of N,N-dimethylacetamide. The method gives an expedient access to propargylic amines in good to excellent yields. A wide-ranging substrate scope and late-stage functionalization of complex molecules make the protocol practically valuable
