The planar structure of a newly reported group of bacterial sulfur-containing aminolipids was revised and their absolute configuration determined by a combination of analytical techniques, isolation, degradation experiments, and total synthesis. The revised structures, termed cysteinolides, diverge from previous homotaurine-based proposals, revealing a composition of a cysteinolic acid containing head
对新报道的一组细菌含硫氨基脂的平面结构进行了修改,并通过分析技术、分离、降解实验和全合成的结合确定了它们的绝对构型。修改后的结构被称为半胱氨酸内酯,与之前基于同牛磺酸的提议不同,揭示了含有被各种(α-羟基)羧酸酰化的头基的半胱氨酸的组成。
