Iron-Catalyzed Oxidative C(3)–H Functionalization of Amines
摘要:
Fe-catalyzed direct dehydrogenative C(3)-functionalization of tertiary arylamines was developed via activation of the sp(3) C(3)-H bond. The reaction is applicable to both cyclic and acyclic amines. The key process is the catalytic desaturative enamine formation from tertiary amines and position-selective C-C bond formation (addition to nitro olefins) at the beta-carbon. Products can be converted to versatile and unique nitrogen-containing molecules.
Discovery of novel and potent lead molecules for the specific therapeutic targets by denovodrugdesign is still in infancy. Here, we disclose the unprecedented development of imidazopyri(mi)dine-based tumor pyruvate kinase M2 (PKM2) modulators by subsequent link and grow strategy. The most potent modulator 15n acts as a PKM2 activator with an AC50 of 90 nM, with considerable cancer cell-selectivity

Heterocyclic compounds as Weel inhibitors are provided. The compounds may find use as therapeutic agents for the treatment of diseases and may find particular use in oncology.
palladium-catalyzed benzylic-like nucleophilic substitution of benzofuran-2-ylmethyl acetate with N, S, O and C soft nucleophiles has been investigated. The success of the reaction is dramatically influenced by the choice of catalytic system: with nitrogen based nucleophiles the reaction works well with Pd2(dba)3/dppf, while with sulfur, oxygen and carbo-nucleophiles [Pd(η3-C3H5)Cl]2/XPhos is more efficient
Novel cerebroprotective agents with central nervous system stimulating activity. 1. Synthesis and pharmacology of the 1-amino-7-hydroxyindan derivatives
To develop a novel cerebroprotective agent with centralnervoussystem (CNS) stimulating activity, a series of 1-amino-7-hydroxyindan derivatives was synthesized, and their effects on the survival time of mice under hypoxic conditions were tested. CNS-stimulating activity was also evaluated by examining the promotional effect on the recovery from cerebral concussion induced coma in mice. Several compounds
