A green and highly efficient synthetic method for the synthesis of quinazoline-2,4-diones with hydrogen peroxide as the terminal oxidant has been developed, The reaction features the mild reaction conditions, broad substrate scope, metal-free catalysts, and sole byproduct water. A plausible mechanism for this process was proposed. Moreover, an antibacterial activity study was performed to evaluate the antimicrobial activities towards two Gram-negative bacterial strains （Escherichia coli, and Klebsiella pneumonia） and two Gram-positive bacterial strains （Staphylococcus epidermidis, and Staphylococcus aureus） using the Broth microdilution method.

A convenient and efficient method was developed for the synthesis of naphtho[2,1-blfurans via 4-dimethylaminopyridine（DMAP）-catalyzed cascade reaction of 2-hydroxy-l-naphthaldehydes and a-halogenated ketones in moderate to good yields in the presence of Na2CO3 at 80 ~C for 6 h. The mechanism for this process was briefly discussed with a tentative catalytic cycle proposed. Moreover, this method features organocatalysts and high step-economy, which makes it practical and attractive.

A convenient and efficient method was developed for the synthesis of 2,2＇-（arylmethylene）bis（3-hydrox- ycyclohex-2-enone） derivatives via the oleylamine-catalyzed tandem Knoevenagel/Michael addition reactions of aromatic aldehydes and cyclohexane-1,3-diones. This transformation proceeded without any metal catalyst in non-toxic solvent at room temperature with high isolated yields. A plausible mechanism for this process was pro- posed.

In this paper, a novel compound 3-（2-qninolyl）-5-ferrocenyl-isoxazole（5） with high selectivity toward Cu2＋ over other heavy and transition-metal（HTM） ions was designed and synthesized in good yields. The compound not only could be used as an electrochemical probe for Cu2＋ with an anodic peak shift of Fe（II）/Fe（III） redox couple, but also could be a colorimetric and fluorescent probe due to the detectable change in color by naked eyes and a significant fluorescence quenching of monomeric anthracene moiety. This highly selective sensing of Cu2＋ may be attributed to the unprecedented intermolecular electron-transfer reorganization after the oxidation of the first single electron of compound 5, as indicated by electrospray ionization mass spectrometry（ESI-MS） and density functional theory（DFT） calculation results. To the best of our knowledge, this class of compounds have rarely been reported in the field of molecular sensing. It may have a potential significance for the application of the ferrocenyl-isoxazole derivative in molecular recognition.

A convenient and metal-flee DMAP-catalyzed domino reaction of isatins, arylamines and hydroximoyl chlorides has been developed to achieve 1,3-dipolar cycloaddition of imines into aryl nitrile oxides at ambient tempera- ture. In this one-pot transformation, a 1,2,4-oxadiazole skeleton was efficiently formed. This methodology needs no extra additives and features wide substrate scope, good functional group tolerance and mild reaction conditions. A plausible mechanism for this process was proposed. Moreover, the antibacterial activities of the products were evaluated towards Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae using the Broth microdilution method.

现象学存在主义通过20世纪法国哲学三大主题(语言、身体、他者)的转向合谋瓦解了早期现代以内在性为指向的意识哲学、主体形而上学。戈达尔的电影将现象学存在主义所建构存在(being)的中心命题进行了影像化的表达,其早期电影的特性具体表现为:非中心化叙事的散文电影、身体出场的体感扩充及他者浮现的相对他性三个方面。而二者背后的哲学理路共同指向了在主体性形而上学瓦解的过程中所产生的当代法国哲学的现代性危机。
