HCl, generated in situ from 2,4,6-trichloro[1,3,5]triazine (TCT, cyanuric chloride), catalyzed a solvent free Hantzsch reaction at room temperature with enhanced reaction rates. The reaction conditions allow facile preparation of glycoconjugates of dihydropyridines under mild reaction conditions in high yields.
由2,4,6-三氯[1,3,5]三嗪(TCT,氰尿酰氯)原位生成的HCl,在室温下催化了一项无溶剂的Hantzsch反应,并显著提高了反应速率。该反应条件使得在温和的反应条件下,能够以高产率便捷地制备二氢吡啶的糖共轭物。
