C-GLUCOSYLARENES FROM O-alpha-D-GLUCOSYL-TRICHLOROACETIMIDATES. STRUCTURE OF BERGENIN DERIVATIVES

C-Glucosylation of oxysubstituted benzene derivatives with O-alpha-D-glucopyranosyl trichloroacetimidate gave mainly beta-D-glucopyranosylarenes.The most efficient catalysts were diethyl ether*boron trifluoride, diethyl ether*zinc chloride and zinc chloride.The reaction was successful with fully and partially O-protected phloroglucinols and it was also compatible with an additional C-alkyl substituent.Introduction of an electron-withdrawing, C-acetyl substiuent into the phloroglucinol structure lowered the reactivity.The reaction could be extended to 1,2,3- and 1,2,4-trioxysubstituted benzene derivatives to give the bergenin derivative (3R,4R,4aR,10bS)-3,4-diacetoxy-2-acetoxymethyltetrahydropyrano<5,6-C>-3,4-dihydroisocoumarin via an intramolecular version of this reaction.O-Protected resorcinols and C-substituted derivatives of dioxysubstituted benzenes gave various 4-C-glucosyl-benzene and chroman derivatives.An anomeric mixture of C-glucosyl derivative of anthrone was obtained from 9-trimethylsiloxyantracene (as a monoxysubstituted benzene derivative).The pure beta-D anomer was synthesized from the O-acylated trichloroacetimidate.

Optimization of 5,6,7,8-tetrahydropyrido[4,3-d]pyrimidines to generate a highly selective PI3Kdelta inhibitor

Chemical optimization of the 5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (THPP) scaffold was conducted with a focus on cellular potency while maintaining high selectivity against PI3K isoforms. Compound 11f was identified as a potent, highly selective and orally available PI3Kdelta inhibitor. In addition, 11f exhibited efficacy in an in vivo antibody production model. The desirable drug-like properties and in vivo efficacy of 11f suggest its potential as a drug candidate for the treatment of autoimmune diseases and leukocyte malignancies.

The synthesis and application of novel Ni(ii) N-alkyl dipyridylaldiminato complexes as selective ethylene oligomerisation catalysts

A series of N-alkyl 2,2?-dipyridylamine ligands of general formula (2-C5H3NR)2NR?, (a): R = H, R? = Me; (b): R = H, R? = benzyl; (c): R = H, R? = methylcyclohexyl; (d): R = H, R? = neopentyl; (e): R = Me, R? = Me) were prepared by a modified method involving base-mediated N-alkylation with the respective alkyl halide. Reaction of the ligands, a-e, with NiCl2(DME) allowed for the isolation of mu-Cl Ni(ii) complexes: [Ni(mu-Cl){a}Cl]2 (1a); [Ni(mu-Cl){b}Cl]2 (1b); [Ni(mu-Cl){c}Cl]2 (1c); [Ni(mu-Cl){d}Cl]2 (1d) and [Ni(mu-Cl){e}Cl]2 (1e). The complexes were characterised by FT-IR spectroscopy, magnetic susceptibility measurements, mass spectrometry, elemental analyses and in the case of 1a, SCD analysis. In the case of complex 1e, an acid-mediated hydrolysis process was identified. The product of hydrolysis, the protonated ligand and a tetrachloronickelate salt (1e-A), was characterised by SCD analysis. Activation of 1a-1e with alkyl aluminium reagents generated highly active catalysts for the oligomerisation of ethylene, with activities of up to 864 kg oligomers molNi-1 h-1 and high selectivity toward the formation of butenes. In general, trans 2-butene was observed as the major isomer, with the exception of 1e. In the case of 1e, the selectivity for 1-butene was 98%, thereby demonstrating the significant effect that the introduction of a low degree of steric pressure in the coordination sphere of the catalyst has on selectivity.

Synthesis and cyanide anion recognition of a new displacement fluorescence chemosensor based on two-branched aurone

A new fluorescence turn-on chemosensor based on two dipyridylamine groups substituted aurone moiety, 4?-2,2?-dipyridylamine-3-2,2?-dipyridylamine aurone (1), was synthesized. The recognition properties of the compound for cyanide anions and copper ions were investigated. Yellow fluorescence of the compound is almost quenched completely because of the complexation between the compound and copper ions. After the subsequent addition of cyanide anions, fluorescence spectrum is recovered to the original status of the compound owing to the strong bonding ability between cyanide anions and copper ions and the removal of copper ions from the complexes. The recognition also can be observed by naked eye. The compound exhibits a good reversibility and can be used repeatedly to recognize cyanide anions for several times.
