The total synthesis of the pyridine−thiazole-containing natural product WS75624 B (1) is described. This synthesis proceeds via the Stille coupling of appropriately functionalized pyridine and thiazole components, and this paper details our studies on the use of the halogen dance reaction to prepare the desired thiazole. Various halogen dance reactions on thizoles are described, including a novel one-pot
描述了含吡啶-噻唑的天然产物WS75624 B(1)的总合成。该合成通过适当官能化的吡啶和噻唑组分的斯蒂勒偶联进行,并且本文详细介绍了我们关于使用卤素舞反应制备所需噻唑的研究。描述了在噻唑上的各种卤素舞反应,包括新颖的一锅多步反应,其中在-78°C的甲硅烷基氯存在下,用LDA处理2-溴噻唑,并用亲电试剂淬灭,以提供高度官能化的噻唑衍生物27。
