“…[1][2][3] These disaccharides are found as the structural units in natural products such as tunicamycins, [4,5] trehalosamines, [6,7] everninomicins, [8,9] and avilamycins. [10,11] Trehaloseg lycolipids contain a1 a!1'a disaccharide core that is desymmetrized with fatty acids and, on some occasions, functionalized with as ulfate group. [12] Examples of these glycolipids include sulfolipids and trehalosedimycolates of Mycobacterium tuberculosis, [13][14][15][16] trehalose dicorynomycolateso fCorynebacterium sp., [12] and maradolipids of Caenorhabditise legans.…”
