Paragraph 0035-0037; 0042-0044; 0049-0051, (2018/04/26)
The invention discloses a method for synthesizing 1-(3-aminopropyl)imidazole from imidazole. The method comprises the following steps: a, adding 28-32 parts by weight of the imidazole, 55-65 parts byweight of acrylonitrile, and 0.9-1.1 parts by weight of ethyl acetate into a reaction kettle, rapidly raising the temperature to 42-44 DEG C under sealed conditions, and performing stirring continuously for 22-28min; and introducing a nitrogen gas for cooling until the temperature is -5 DEG C, adding dilute sulfuric acid to adjust the pH value to 2.2-2.4, and performing stirring for 10-20min for precipitating a crystal; b, washing the crystal with saturated salt water, performing vacuum drying, and performing cooling to normal temperature to obtain N-(2-cyanoethyl)imidazole and other steps. The preparation method provided by the invention is scientific and simple, strictly controls the formula ratio, and controls the reaction conditions, the raw materials are easy to obtain, the usage amount of the raw materials is small, the cost is low, and the prepared 1-(3-aminopropyl)imidazole has high purity, a high yield and stable performance, and is suitable for industrialized production.

Herein, we report the development of biohybrid catalysts that are capable of catalyzing the aldol reaction. The use of biotinylated imidazolium salts in combination with racemic or enantiomerically pure catalytic anions allowed us to study the adaptive and cooperative positioning of the anionic catalyst inside the protein. Supramolecular encapsulation of the biotinylated catalyst into avidin resulted in good selectivity for the aldol reaction performed in ionic liquid/water mixtures. Biohybrid catalysts capable of catalyzing the aldol reaction are prepared from avidin and biotinylated imidazolium salts with either racemic or enantiomerically pure catalytic anions. Supramolecular encapsulation (see figure) of the biotinylated catalyst in avidin resulted in good selectivities for the aldol reaction when performed in ionic liquid/water mixtures and the adaptive and cooperative positioning of the anionic catalyst inside the avidin protein is discussed.
