The phthiocerols, RCH(OMe)·CHMe·[CH2]4·CH(OH)·CH2·CH(OH)·[CH2]nMe (R = Et or Me, n= 20 and 22), constituents of tuberculolipids, have been converted, by substituting H for each OH, into the corresponding methoxyphthioceranes A and B (R = Et or Me, respectively). An optically active diastereoisomer of the latter and structurally related model compounds have been synthesized. By comparison of the methoxyphthioceranes
邻苯二酚RCH(OMe)·CHMe·[CH 2 ] 4 ·CH(OH)·CH 2 ·CH(OH)·[CH 2 ] n Me(R = Et或Me,n = 20和22),组成通过用H代替每个OH,可将一部分结核脂质转化为相应的甲氧基苯硫醚铈烷A和B(分别为R = Et或Me)。已经合成了后者的旋光性非对映异构体和与结构相关的模型化合物。通过比较甲氧基苯硫杂环戊烷与合成产物,将带有甲氧基和甲基支链的不对称中心分配为苏-构型,按照在JCS Perkin I中定义的意义使用苏-,1973,109。
