Tuberculostearic acid, (R)-10-methyloctadecanoic acid, is a characteristic component of pathogenic mycobacteria and related organisms. Sensitive detection of this acid in infected material allows rapid detection of mycobacterial disease. A novel, convergent synthesis of tuberculostearic acid and key chiral intermediates is described in this communication, to provide a reference compound. Racemic and
结核硬脂酸(R)-10-甲基十八烷酸是致病性分枝杆菌和相关生物的特征性成分。灵敏地检测受感染物质中的这种酸可以快速检测出分枝杆菌疾病。在本文中描述了结核硬脂酸和关键手性中间体的新颖,收敛的合成,以提供参考化合物。外消旋和(R)-和(S)-1-碘-2-甲基癸烷是由1-辛醇和1-羰基乙氧基亚乙基三苯基膦作为初始原料合成的。1-羟基己-7-炔由1,6-己二醇通过两种替代方法制得,并与上述外消旋碘化物偶联。所得(R,S)-10-甲基十八烷基-7-yn-1-ol的氢化和氧化得到外消旋结核硬脂酸。
