Chinese Chemical Letters 2013年第3期24卷 257-259页

作者： Bing Zhao Ya-Cui Zhou Meng-liao Fan Zhi-Yu li li-Yan Wang qi-Gang Deng Chemistry and Chemical Engineering Institute Qiqihar University

Three tetraaryl imidazole derivatives 5a-5c bearing thiazole groups were synthesized in the presence of [Bmin]Br by one-pot reaction and their structures were fully characterized by the H NMR, IR, MS and elemental analysis. The results of UV-vis spectra and fluorescent spectra upon metal ions complexation show that compound 5a displays high selectivity and sensitivity for Cr3＋ ions. The complexation ratio of compound 5a and Cr3＋ is 1：1.

Based on the Global Color Symmetry Model, the non-perturbative Q, CD vacuum is investigated in the parameterized fully dressed quark propagator. Our theoretical predictions for various quantities characterized the QCD vacuum are in agreement with those predicted by many other phenomenologieal QCD inspired models. The successful predictions clearly indicate the extensive validity of our parameterized quark propagator used here. A detailed discussion on the arbitrariness in determining the integration cut-off parameter ofμ in calculating QCD vacuum condensates and a good method, which avoided the dependence of calculating results on the cut-off parameter is also strongly recommended to readers.

In this study,we investigate the invariant-mass distribution of top-quark pairs near the 2mt threshold,which strongly influences the determination of the top-quark mass ***-order non-relativistic corrections lead to large contributions,which are not included in the state-of-the-art theoretical predictions.A factorization formula is derived to resum such corrections to all orders in the strong-coupling,and necessary ingredients are calculated to perform the resummation at next-to-leading *** combine the resummation with fixed-order results and present phenomenologically relevant numerical *** resummation effect significantly increases the differential cross-section in the threshold region and makes the theoretical prediction more compatible with experimental *** estimate that using our prediction in the determination of mt will lead to a value closer to the direct measurement result.

One pot synthesis of dibenzodiazepinones via CuI catalysis in ethylene glycol

引用

Chinese Chemical Letters 2013年第9期24卷 825-828页

作者： qing-Yang Zhang Xiao-Jian Wang Yu-lin Tian Jian-Guo qi Chun li Da-li Yin State Key Laboratory of Bioactive Substance and Function of Natural Medicines Beijing Key Laboratory of Active Substance Discovery and Druggability Evaluation Institute of Materia Medica Peking Union Medical College and Chinese Academy of Medical Sciences

A one pot protocol for the synthesis of dibenzodiazepinones was developed. The substituted ethyl 2- halobenzoates are cross-coupled with o-phenylenediamine utilizing a ligand-free, Cul catalyzed system, which spontaneously undergo an intramolecular N-acylation in ethylene glycol to give the corresponding products in high yields. This synthetic protocol provides a concise and efficient access to a wide variety of dibenzodiazepinone, including biologically active molecules.
