Abstract
The chemical structure of tautomycin (C41H66O13) was determined by chemical degradation, spectroscopic analysis and 2D INADEQUATE of tautomycin labeled with [1,2-13C]acetate. Tautomycin exists in methanol-buffer solution (1% diethylamine-formic acid, pH 7.3) as an equilibrium mixture of a 2,3-dialkylmaleic anhydride and its dicarboxylic acid in a ratio of approximately 5:4.
摘要
互隔交链孢酚（C41H66O13）的化学结构通过化学降解、光谱分析以及用[1,2-13C]乙酸酯标记的互隔交链孢酚的二维异核多量子相干谱来确定。互隔交链孢酚在甲醇缓冲溶液（1%二乙胺-甲酸，pH 7.3）中以2,3-二烷基马来酸酐及其二羧酸的平衡混合物形式存在，比例约为5:4。
