2-amino-2-deoxy- d - glycero - d - altro -heptose hydrochloride with acyclic and cyclic 1,3-dicarbonyl compounds gives, respectively, ( d - allo -pentitol-1-yl)-pyrroles and -tetrahydroindoles that can be dehydrated to yield d - ribo - C -glycosyl heterocycles having furanoid or pyranoid structures, depending on the reaction conditions. Thus, when the reactions were kinetically controlled, α- and β- d -ribofuranosyl
摘要2-氨基-2-脱氧-d-甘油-d-α-庚糖盐酸盐与无环和环状的1,3-二羰基化合物反应,分别得到(d-异代-戊醇-1-基)-吡咯和取决于反应条件,可以脱水以产生具有呋喃或吡喃结构的d-核糖-C-糖基杂环的-四氢吲哚。因此,当动力学控制反应时,获得了α-和β-d-呋喃核糖基杂环,但是在热力学控制条件下形成了α-和β-d-核吡喃糖基杂环。提出了基于三乙酸酯的质谱在两种结构之间进行区分的标准。
