A simple, metal-free, and environment-friendly procedure is developed for the direct conversion of esters to amides using ammonium nitrate as a catalystundersolvent-freeconditions. Aryls, hetero...
High-valent chiral oxidovanadium(V) complexes derived from 3,5-substituted-N-salicylidene-l-tert-leucine were used as catalysts in asymmetric reduction of N-benzyl-β-ketoamides. Among six different solvents, three different alcohol additives, and two different boranes examined, the use of pinacolborane in tetrahydrofuran (THF) with a t-BuOH additive led to the best results at -20 °C. The corresponding
Kinetic resolution of 3-hydroxyalkanamides with good to high selectivities was achieved by benzoylation using copper(II) triflate and (R,R)-PhBox [2,2′-isopropylidenebis(4-phenyl-2-oxazoline)] as catalyst, which also mediated enantioselective tosylation of 2,2-bis(hydroxymethyl)alkanamides with high efficiency.
considerable progress has been made in the asymmetric synthesis of trans- and trisubstituted glycidic esters, achieving enantioselective preparation of cis-glycidic esters has remained a long-standing challenge. Here, we demonstrate a selectivity-predictable modular platform for the asymmetric synthesis of cis-glycidic esters via a novel dinuclear (salen)titanium(III)-catalyzed radical-type kinetic resolution
