Novel Process for the Preparation of Nonracemic Long Chain alpha-Amino Acid Derivatives active N-acyl lactam using an organometallic reagent to effect the opening of the ring followed by reduction of the ketone carbonyl to an alcohol or a methylene, or by a reductive amination to an amine, or...
Proline-catalysed asymmetric amination of alpha,alpha-disubstituted aldehydes: synthesis of configurationally stable enantioenriched alpha-aminoaldehydes. Proline-catalysed amination of α,α-disubstituted racemic aldehydes with azodicarboxylates proceeds smoothly to give configurationally stable scalemic ald... ...
An alpha-chloroketone is defined as a compound obtained by the reaction of alpha-dichloroaryltelluroketones with chlorine in dichloromethane, resulting in the formation of corresponding alpha-chloroketones in good yields. AI generated definition based on: Tellurium in Organic Synthesis (Second Edition)...

AMINATIONINSERTIONALCOHOLSHerein we have reported a one-pot green methodology for the synthesis of quinoline tethered alpha-amino ketones. The reaction of arylglyoxal, 2-aminoquinoline, and 4-hydroxy-1-methylquinolin-2(1H)-one/barbituric acid in ethanol under reflux conditions provided the quinoline ...
The catalytic enantioselective electrophilic alpha-amination promoted by chiral palladium complexes is described. Treatment of alpha-cyanoketones with azodicarboxylates as electrophilic amination reagents under mild reaction conditions afforded the corresponding alpha-amino alpha-cyanoketones with excellent ...
