, p. 63 - 66 (2005)
(Chemical Equation Presented) The synthesis of two flexible nucleosides is presented. The fleximers feature the purine ring system split into its imidazole and pyrimidine components. This modification serves to introduce flexibility to the nucleoside while still retaining the elements essential for molecular recognition. As a result, these structurally innovative nucleosides can more readily adapt to capricious binding sites and, as such, should find use for investigating enzyme-coenzyme as well as nucleic acid-protein interactions.

Paragraph 0153; 0154; 0155; 0166; 0167, (2018/05/07)
The invention relates to a manufacturing method of nitrile. Compared with the prior art, the manufacturing method has the characteristics of significantly reduced using amount of an ammonia source, low environmental pressure, low energy consumption, low production cost, high purity and yield of a nitrile product and the like, and nitrile with a more complex structure can be obtained. The invention also relates to a method for manufacturing corresponding amine from nitrile.
Synthetic method of histamine dichloride

Paragraph 0008; 0012, (2017/03/24)
The invention discloses a synthetic method of histamine dichloride, and belongs to the field of drug synthesis. The synthetic method comprises the following steps: preparing a cyano methylimidazole intermediate through oxidization of TCCA (Trichloroisocyanuric Acid) under an alkaline condition by taking L-histidine as an original raw material, and then preparing medicinal histamine dichloride through catalytic hydrogenation and one-step salifying process. In the histamine dichloride compounded through the synthetic method, the content of related substances is less than 0.5 percent, the content of a single impurity is less than 0.1 percent, and the histamine dichloride accords with medicinal level. A reagent adopted by the technology is cheap and of low-toxicity, the reaction is safe and reliable, an alcohol solvent can be recycled, after-treatment operation is simple and convenient, and the technology is environment-friendly and is beneficial for large-scale industrial production.
