Total synthesis of yersiniabactin, a siderophore from cultures of the bacterium Yersinia enterocolitica, was accomplished. Chirality at the readily racemizable C-9 carbon was preserved during cyclization of β-hydroxythioamide by means of Burgess reagent leading to thiazoline. Based on its synthesis, the absolute configuration of natural yersiniabactin has been determined as 9R, 10RS, 12R, 13S and 19S
完成了耶尔西菌素的全合成,这是一种来自小肠结肠炎耶尔森氏菌培养物的铁载体。在β-羟基硫酰胺的环化过程中,通过伯硫试剂生成噻唑啉,可以保持易于消旋的C-9碳的手性。根据它的合成,天然耶尔森杆菌的绝对构型已被确定为9 - [R,10个RS,12 - [R,13小号和19小号。
