Three pyochelin analogues and their methyl esters all containing a thiazole ring have been synthesised from the same Weinreb amide key intermediate. One of these analogues called HPTT-COOH, a molecule released in the course of pyochelin and yersiniabactin biosynthesis, was efficiently synthesised using a new base induced conversion of the key compound 2′-(2-hydroxyphenyl)-2′-thiazoline-4′-(N-methoxy
从相同的Weinreb酰胺关键中间体合成了三种均含有噻唑环的pyyochelin类似物及其甲酯。使用新的碱诱导的关键化合物2'-(2-羟苯基)-2'-噻唑啉-4'的新转化,可以有效地合成其中一种称为HPTT-COOH的类似物,这是在Pyochelin和yersiniabactin生物合成过程中释放的分子。 -(N-甲氧基,N-甲基)羧酰胺成2'-(2-羟苯基)-2'-噻唑-4'-(N-甲氧基,N-甲基)羧酰胺。
