The present invention relates to new endoperoxide compounds and compositions, and to a process for producing them for prophylaxis and control of perkinsiosis in bivalves. Endoperoxide compounds with biological activity against Perkinsus olseni include 13 trioxolanes and 9 tetraoxanes. Protozoan parasites of the genus Perkinsus are known to infect several species of marine molluscs worldwide, like oysters, abalones, clams, scallops, pearl oysters, cockles or mussels. The present invention also describes the synthesis of these compounds, in particular of new endoperoxide compounds of the tetraoxane family. Compositions comprising endoperoxide compounds are useful for prophylaxis and control of perkinsiosis in bivalves. Therefore, the present invention also relates to a method of controlling perkinsiosis in bivalves. The present invention is in the domain of aquaculture, medicine, pharmaceuticals and biochemistry.

2-Arylindoles were prepared by a sequential reaction of Ag-catalyzed α-addition–Pd-catalyzed C–H bond functionalization of tetrazoles with bromoalkynes. A stereocontrolled Ag-catalyzed α-addition reaction of tetrazoles with bromoalkynes underwent smoothly to generate (Z)-N-(2-bromo-1-vinyl)-N-arylcyanamides, which were subsequently converted into 2-arylindoles through an intramolecular cyclization by Pd-catalyzed direct C–H bond functionalizations.
通过四唑与溴炔的 Ag 催化 α-加成-Pd 催化 C-H 键官能化的顺序反应制备了 2-芳基吲哚。在 Ag 催化下,四唑与溴炔发生了立体控制的 α 加成反应,顺利生成了 (Z)-N-(2-溴-1-乙烯基)-N-芳基氰酰胺,随后通过 Pd 催化的直接 C-H 键官能化反应将其分子内环化为 2-芳基吲哚。

Regarding green chemistry goals, silica-coated magnetite nanoparticles open up a new avenue to introduce a very useful and efficient system for facilitating catalyst recovery in different organic reactions. Therefore, in this paper the preparation of sulfonic acid-functionalizedsilica-coatedmagneticnanoparticles with core–shell structure (Fe3O4@silica sulfonic acid) is presented by using Fe3O4 spheres
关于绿色化学目标,二氧化硅涂覆的磁铁矿纳米粒子开辟了一条新途径,以引入非常有用和高效的系统,以促进催化剂在不同有机反应中的回收。因此,本文提出了使用Fe 3 O 4制备具有核-壳结构的磺酸官能化二氧化硅包覆的磁性纳米粒子(Fe 3 O 4 @二氧化硅磺酸)的方法。球体为核心,二氧化硅磺酸盐纳米粒子为壳。通过红外光谱,扫描电子显微镜,X射线衍射分析,动态光散射,热重分析和振动样品磁强分析对催化剂进行了表征。可以使用外部磁体回收纳米催化剂,并将其重复用于后续反应6次,而不会明显降低催化活性。
