| Glutarimide Usage And Synthesis |
| Chemical Properties | white crystalline powder | | Uses | Glutarimide acts as an inhibitor of protein synthesis. Further, it is used as a reactant for thionations and biocatalytic asymmetric synthesis of sitagliptin production. It is also employed in the generation of beta-adrenoceptor ligands, enantioselective synthesis of securinega alkaloids and alfa-fluoro-alfa amino amides. In addition to this, it is used in intramolecular amidocyclopropanation reactions. | | Definition | ChEBI: A dicarboximide that is piperidine which is substituted by oxo groups at positions 2 and 6. | | Preparation | To a flask containing 70 gm (0.53 mole) of glutaric acid is added 150 ml (2.2 mole) of 28% aqueous ammonia. The mixture is set for distillation and heated for 7 hr as the temperature of the mixture rises from 90° to 180°C. The temperature is held at 170-180°C for \\ hr or until the evolution of ammonia ceases. The reaction mixture solidifies on cooling and the product is recrystallized from acetone to afford 37.4 gm (63%), m.p. 145-146°C.
t may be advantageous to preform the ammonium salt of dicarboxylic acids prior to the application of enough heat to form the imide. The preparation of succinimide is a case in point.
| | General Description | A glutarimide antibiotic, 9-methylstreptimidone, shows antiviral, antitumor and antifungal activities. | | Purification Methods | Purify it by dissolving 75g in 200mL of H2O, boil for 30minutes with 2g of charcoal, filter, evaporate to dryness and recystallise the residue from 125mL of 95% EtOH to give 70g of white crystals, m 152-154o. It also crystallises from Me2CO (m 163-165o) or EtOH (m 153-154o). The N-bromo derivative (a brominating agent) crystallises from H2O with m 180-185o. [Paris et al.
