A 1,4-dihydropyridine derivative with bulky aryl substituents and no carbonyl groups was synthesized and found to possess high hydride donating ability, acid resistance, and reusability. Thermodynamic parameters for electron and hydride transfer in the redox system were determined, and the compound was shown to promote efficient, selective reduction reactions under mild conditions.
A 1,4-dihydropyridine derivative, lacking carbonyl groups and containing bulky aryl substituents, was synthesized and found to have a high hydride donating ability, acid resistance and reusability. Thermodynamic parameters for electron and hydride transfer in the redox system comprising the 1,4-dihydropyridine and its corresponding pyridinium ion were determined. In addition, studies showed that the 1,4-dihydropyridine with steric hindrance can be used to promote efficient, boron trifluoride catalyzed selective reduction reactions of aldimines and aldehydes under mild conditions.
