The preparation of three analogues of the putative diketide biosynthetic precursor (2) and eight analogues of the putative triketide biosynthetic precursor (3) of the acyl tetronic acid ionophore tetronasin, as N-acetylcysteamine thioesters (4), (5), (6), (12), (13), (14), (15), (22), (23), (24) and (25) is described. Five examples are 19F-labelled; a new, enantiospecific method for the creation of
的推定二酮生物合成前体的3个类似物(制备2)和八个类似物推定三酮的生物合成前体(3酰基季酮酸离子载体tetronasin,如N-乙酰半胱胺硫酯(的)4),(5),(6)描述了(12),(13),(14),(15),(22),(23),(24)和(25)。有五个例子是19 F标记的;提出了一种新的,对映体特异性的方法,用于创建氟化季铵α-中心。
