Reductive Amination of Aldehydes and Ketones with Sodium Triacetoxyborohydride. Studies on Direct and Indirect Reductive Amination Procedures(1).
Sodium triacetoxyborohydride is presented as a general reducing agent for the reductive amination of aldehydes and ketones. Procedures for using this mild and selective reagent have been developed for a wide variety of substrates. The scope of the reaction includes aliphatic acyclic and cyclic ketones, aliphatic and aromatic aldehydes, and primary and secondary amines including a variety of wea...
متن کاملThe reductive amination of aldehydes and ketones by catalytic use of dibutylchlorotin hydride complex.
The reductive amination of aldehydes or ketones using Ph(2)SiH(2) or PhSiH(3) has been effectively promoted by the direct use of Bu(2)SnClH-pyridine N-oxide as a catalyst; this method has advantages in terms of its mild conditions and wide application to various carbonyls and amines, including aliphatic examples.
متن کاملOne-pot reductive Amination of Carbonyl Compounds using NaBH4 and Fe3O4 Magnetic Nanoparticles
One-pot reaction of aldehydes or ketons with aniline derivatives was performed using NaBH4 and Fe3O4 magnetic nanoparticles (MNPs). The optimum amount of Fe3O4 MNPs was 5 mol% under solvent free condition. The corresponding products were obtained in good to excellent yields. The magnetically recoverable iron oxide nanoparticles are found to be efficient for synthesis of amine derivatives. These...
متن کاملBoric Acid: As a Green Catalyst for the Conversion of Aldehydes and Ketones to Gem-Dihydroperoxides Using Aqueous 30% H2O2
Gem-dihydroperoxides as nearly stable peroxidic derivatives of aldehydes and ketones are known important intermediates in synthesis of anti-malaria drugs. Also, because containing high concentration of peroxidic oxygen, recently, some of these compounds have been used as solid, efficient and powerful oxidants in many oxidation organic reactions. Generally, these compounds are synthesiz...
متن کاملReductive amination of tertiary anilines and aldehydes.
An unprecedented oxidant-mediated reductive amination of tertiary anilines and aldehydes without external reducing agents was developed via the nucleophilic attack of the oxygen atom of the carbonyl group to in situ generated iminium ions, in which tertiary anilines were used as both nitrogen source and reducing agent for the first time.
