The synthesis is described of adiposin-1 (2a), isolated from an α-d-glucosidase inhibitor complex, adiposin, produced by Streptomyces caluvs TM-521. The synthesis involved the coupling of 1,6-anhydro-4-O-(3,4-anhydro-α-d-galactopyranosyl)-β-d-glucopyranose (13) with the di-O-isopropylidene derivative (7) of dl-(1,4,65)-4,5,6-trihydroxy-3-(hydroxymethyl)-2-cyclohexenylamine. All possible diastereoisomers
描述了脂链素-1(2a)的合成,该脂链素-1(2a)是从产自链霉菌TM-521的α-d-葡萄糖苷酶抑制剂复合物脂腺素中分离出来的。合成过程涉及将1,6-脱水-4-O-(3,4-脱水-α-d-吡喃半乳糖基)-β-d-吡喃葡萄糖(13)与的二-O-异亚丙基衍生物(7)偶联。 dl-(1,4,65)-4,5,6-三羟基-3-(羟甲基)-2-环己烯基胺。通过硅胶色谱分离所有可能的仲胺非对映异构体。根据1H-nmr光谱学和旋光性初步确定了它们的结构。同样地,合成脂蛋白的核心结构(4)和2a的饱和类似物(22)。
