From simple beginnings: A novel Cu‐promoted direct incorporation of nitrogen into simple hydrocarbon molecules under mild and neutral reaction conditions is described. 1,5‐Disubstituted tetrazoles are efficiently constructed by two CH and one CCbondcleavages (see scheme; TMS=trimethylsilyl). This protocol provides a new and unique strategy to functionalize simple and readily available hydrocarbon

A mild and convenient oxidativetransformation of secondaryalcohols to 1,5‐disubstituted tetrazoles is uncovered by employing trimethylsilyl azide (TMSN3) as a nitrogen source in the presence of a catalytic amount of copper(II) perchlorate hexahydrate [Cu(ClO4)2.6 H2O] (5 mol%) and 2,3‐dichloro‐5,6‐dicyano‐para‐benzoquinone (DDQ) (1.2 equiv.) as an oxidant. This reaction is performed under ambient
在催化量的高氯酸铜(II)六水合物[Cu(ClO 4)]存在下,通过使用三甲基叠氮化硅(TMSN 3)作为氮源,发现了中等程度的醇向1,5-二取代的四唑进行温和且方便的氧化转化。2 。6 H 2 O](5 mol%)和2,3-二氯-5,6-二氰基对苯醌(DDQ)(1.2当量)作为氧化剂。该反应在环境条件下进行,并通过CC键裂解进行。
Estrogenic Activity of Tetrazole Derivatives Bearing Bisphenol Structures: Computational Studies, Synthesis, and In Vitro Assessment
worldwide are researching to develop non-ER binding starting compounds to fulfill unmet market needs. In line with this trending research topic, the current paper highlights the development of tetrazole derivatives bearing a bisphenol structure (TbB) as a novel weak binder or potential inactive to the estrogen receptor (ER) and androgen receptor (AR). The structure and ligand-based approach supported by binding
