  Synthesis of Carbohydrates in Mineral-Guided Prebiotic Cycles

  摘要：

  One present obstacle to the "RNA-first" model for the origin of life is an inability to generate reasonable "hands off" scenarios for the formation of carbohydrates under conditions where they might have survived for reasonable times once formed. Such scenarios would be especially compelling if they deliver pent(ul)oses, five-carbon sugars found in terran genetics, and exclude other carbohydrates (e.g., aldotetroses) that may also be able to function in genetic systems. Here, we provide detailed chemical analyses of carbohydrate premetabolisin, showing how borate, molybdate, and calcium minerals guide the formation of tetroses (C(4)H(8)O(4)), heptoses (C(7)H(14),O(7)), and pentoses (C(5)H(10)O(5)), including the ribose found in RNA, in "hands off" experiments, starting with formaldehyde and glycoaldehyde. These results show that pent(ul)oses would almost certainly have formed as stable borate complexes on the surface of an early Earth beneath a humid CO(2) atmosphere suffering electrical discharge. While aldotetroses form extremely stable complexes with borate, they are not accessible by pathways plausible under the most likely early Earth scenarios. The stabilization by borate is not, however, absolute. Over longer times, material is expected to have passed from borate-bound pent(ul)oses to a branched heptulose, which is susceptible to Cannizzaro reduction to give dead end products. We show how this fate might be avoided using molybdate-catalyzed rearrangement of a branched pentose that is central to borate-moderated cycles that fix carbon from formaldehyde. Our emerging understanding of the nature of the early Earth, including the presence of hydrated rocks undergoing subduction to form felsic magmas in the early Hadean eon, may have made borate and molydate species available to prebiotic chemistry, despite the overall "reduced" state of the planet.

  摘要：

  合成了一系列呋喃糖和吡喃糖形式的碳水化合物的异头硝酸酯和N-邻苯二甲酰亚胺基糖苷，以生成相应的烷氧基，并研究还原条件下的C1-C2片段化反应。该反应构成了将碳水化合物转化为碳较少的相应糖醇的两步法。使用这种方法，已经制备了具有D-赤藓糖醇，D-苏糖醇，D-木糖醇和D-阿拉伯糖醇立体化学的天然产物合成的有趣的四碳和五碳构件。1,2-O-异亚丙基-β-L-苏糖（40）和1-乙酰氨基-2,4,5-三-O-乙酰基-D-阿拉伯糖醇（50）的合成也已从1,2实现：5,6-二-O-异亚丙基-β-D-呋喃葡萄糖和2-乙酰氨基-3,4,6-三-O-乙酰基-2-脱氧-D-吡喃葡萄糖，

  4-di- O -methyl- l -iditol ( 7 ), respectively. The cyclization of 3 and 5 is a novel method for obtaining 1,6-anhydro-3,4-di- O -methyl- d -mannitol ( 11 ) and a stereoselective route to 1,5-anhydro-3- O -methyl- l -arabinitol ( 13 ). It is proposed that the reaction occurs via endo -selective cyclization of an epoxy alcohol produced by the endo -selective ring-opening of one of the two epoxide moieties
