  “Locked-ring” C-glycoside derivatives may be prepared wherein the ring of the sugar molecule remains intact without the need for any protecting groups. These C-glycoside derivatives may be produced by first reacting an aldose reducing sugar, which may be a hexose or a pentose, with a β-diketone to form a C-glycoside ketone. The C-glycoside ketone is then reacted with a ketone reactive compound, such as a hydrazine or hydroxylamine, optionally linked to a detectable label, to form a C-glycoside derivative wherein the ketone reactive compound is conjugated to the C-glycoside at the site of the ketone. The aldose reducing sugar used in the first reaction may a simple pentose or hexose monosaccharide, or it may be optionally substituted.

  可以制备“锁定环”C-糖苷衍生物，其中糖分子的环保持完整，无需任何保护基团。这些C-糖苷衍生物可以通过首先将醛糖还原糖（可以是己糖或戊糖）与β-二酮反应以形成C-糖苷酮。然后，将C-糖苷酮与酮反应性化合物（如肼或羟胺，可选地连接到可检测的标记）反应，形成一个C-糖苷衍生物，其中酮反应性化合物与C-糖苷在酮的位置结合。在第一反应中使用的醛糖还原糖可以是简单的戊糖或己糖单糖，也可以是可选择地取代的。

  The present invention is directed to a method for preparing renewable and relatively high purity p-xylene from biomass. For example, biomass treated to provide a fermentation feedstock is fermented with a microorganism capable of producing a C4 alcohol such as isobutanol, then sequentially dehydrating the isobutanol in the presence of a dehydration catalyst to provide a C4 alkene such as isobutylene, dimerizing the C4 alkene to a form one or more C8 alkenes such as 2,4,4-trimethylpentenes or 2,5-dimethylhexene, then dehydrocyclizing the C8 alkenes in the presence of a dehydrocyclization catalyst to selectively form renewable p-xylene in high overall yield. The p-xylene can then be oxidized to form terephthalic acid or terephthalate esters.

  本发明涉及一种从生物质制备可再生和相对高纯度对二甲苯的方法。例如，经过处理以提供发酵原料的生物质与能够产生C4醇（如异丁醇）的微生物发酵，然后在脱水催化剂的存在下顺序脱水异丁醇以提供C4烯烃（如异丁烯），将C4烯烃二聚化为一个或多个C8烯烃（如2,4,4-三甲基戊烯或2,5-二甲基己烯），然后在去氢环化催化剂的存在下去氢环化C8烯烃以有选择性地形成高总产率的可再生对二甲苯。然后，对二甲苯可以氧化形成对苯二甲酸或对苯二甲酸酯。
