Thieno[2,3-d]isothiazoles were synthesized as potential plant a ctivators. Based on previously reported thienothiadiazole plant activators, one ri ng nitrogen was eliminated from the bicyclic motif in order to extend structure activity relatio nship information. Thieno[2,3-d]isothiazoles bearing different functional groups were prepared s tarting from readily available 3,4dibromothiophene. Introduction
合成噻吩并 [2,3-d] 异噻唑作为潜在的植物活化剂。基于先前报道的噻吩并噻二唑植物活化剂,从双环基序中消除了一个环氮以扩展结构活性关系信息。具有不同官能团的噻吩并[2,3-d]异噻唑从容易获得的3,4二溴噻吩开始制备。在噻吩系统的 1 位和 2 位引入肟和甲硫基为环化奠定了基础,在甲磺酰氯存在下将肟转化为更具反应性的肟酯后,环化反应自发发生。
