Nano Silica Phosphoric Acid: An Efficient Catalyst for the One- Pot Synthesis of 1, 2, 4, 5-Tetrasubstituted Imidazoles
Two simple protocols for the synthesis of 1, 2, 4, 5- tetrasubstitutedimidazoles using nano-SPA as a reusable, eco- friendly, inexpensive, and efficient catalyst are reported. Short reaction times, high yields, scale-up and easy workup are the advantages of these protocols.
متن کاملTHE ISOLATION AND SYNTHESIS OF GLUCOSE-l- PHOSPHORIC ACID*
Glucose-l-phosphoric acid was first isolated from minced and washed frog muscle which had been incubated for 3 hour in phosphate buffer containing small amounts of adenylic acid (2). Under these conditions part of the glucose-l-phosphoric acid (l-ester) was converted to hexose-6-phosphoric acid (8ester), so that fractional crystallization of the brucine salts had to be resorted to as a means of...
متن کاملEnzymatic hydrolysis of adenosine 3',5'-phosphoric acid.
During recent years the work of Sutherland and his associates (l-3) on the liver phosphorylase system has done much to clarify the mechanism of epinephrine-induced hyperglycemia. These workers have shown that epinephrine stimulates glycogenolysis by increasing the level of active phosphorylase in dog liver slices (3, 4) and in cell-free homogenates (5). The effect of epinephrine was shown to be...

متن کاملElectrochemical Synthesis of 5-Aminosalicylic Acid from 5- Nitrosalicylic Acid in Alkaline Media
5-Aminosalicylic acid (5-ASA) is currently prepared by electrochemical reduction of 5-nitrosalicylic acid (5-NSA) in acidic media. In this work, electrolytic reduction of 5-NSA in alkaline media is presented. Reactionconditions and parameters such as anode and cathode electrodes, electrolyte type, reaction time, temperature,current, and the pH for isolation of product are investigated. The yiel...
