Synthetic Route of 857890-39-2, In homogeneous catalysis, catalysts are in the same phase as the reactants. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 857890-39-2, Name is Lenvatinib Mesylate, SMILES is O=C(C1=C(OC)C=C2N=CC=C(OC3=CC=C(NC(NC4CC4)=O)C(Cl)=C3)C2=C1)N.CS(=O)(O)=O, belongs to quinoxaline compound. In a article, author is Wu, Xianqing, introduce new discover of the category.
Asymmetric Synthesis of alpha-Alkylated gamma-Lactam via Nickel/8-Quinim-Catalyzed Reductive Alkyl-Carbamoylation of Unactivated Alkene
Chiral-auxiliary-mediated synthesis represents the most frequently used synthetic tool for the induction of chirality on alpha-position of gamma-lactams in organic synthesis. However, the general strategy requires the stoichiometric use of chiral reagents with multiple manipulation steps. Transition-metal-catalyzed asymmetric alkene dicarbofunctionalization using readily available substrates under mild conditions allows the simultaneous construction of two vicinal chemical bonds and a chiral carbon center, hence, gain expedient access to chiral heterocycles. Herein, we disclose a Ni-catalyzed enantioselective reaction of 3-butenyl carbamoyl chloride and primary alkyl iodide enabled by a newly designed chiral 8-quinoline imidazoline ligand (8-Quinim). This protocol features broad functional group tolerance and high enantioselectivities, achieving unprecedented synthesis of chiral nonaromatic heterocycles via catalytic reductive protocol.
