Witryna8 kwi 2024 · The general procedure for the imine-synthesis reaction involved stirring the aldehyde (5 mmol) and the amine (5.5 mmol) in the presence of 0.2 g of A15 catalyst … Witryna26 lip 2024 · Ru-catalyzed tandem amine oxidative dehydrogenation/formal aza-Diels–Alder reaction for enantio- and diastereoselective synthesis of indoloquinolizidine-2-ones from tetrahydro-β-carbolines and α,β-unsaturated ketones is described. The reaction proceeds via tandem ruthenium-catalyzed amine dehydrogenation using tert … WitrynaThe mechanism starts with the amine (1) attacking the β carbon of the β-ketoesters (2), and eventually forming an enamine (3).The enamine then attacks the carbonyl carbon of the α-haloketone (4).This is followed by the loss of H 2 O, giving an imine (5).This intermediate undergoes an intramolecular nucleophilic attack, forming a 5-membered … favorite bath and body scent
