Paragraph 0131; 0132-0136, (2017/05/02)
The invention provides an anthracene compound. The anthracene compound has a structure in the formula (I), wherein Q is the C1-60 alkyl group or the C6-60 aryl group or the C5-60 condensed ring group or the C5-60 heterocyclic group; Ar is the C6-60 aryl group or the C5-60 condensed ring group or the C5-60 heterocyclic group; and Ar1 is H, the C1-60 alkyl group, the C1-60 alkoxy group, the C1-60 ether group, the C6-60 aryl group, the C6-60 condensed ring group, the C6-60 heterocyclic group and the C6-60 arylamine group. Compared with the prior art, the anthracene compound is connected with an aromatic compound through anthracene, and the Q, Ar and Ar1 groups are introduced, so that a device emits blue light after the organic compound is applied to the organic light-emitting device; and meanwhile, the means that the above groups are used for adjusting the light-emitting wavelength is adopted, the light-emitting efficiency of the organic light-emitting device is high, and the service life is long.

(Chemical Equation Presented) Step by step: Highly selective cross dehydrogenase arylation of acetanilides was developed to construct biaryls under mild condition. With this method, different aryl C-H bonds were activated in sequential reactions to construct functionalized carbazoles (see scheme), which are present as key structural units in various biological molecules and organic optical materials.

The present invention provides 2-furancarboxylic acid hydrazide compounds represented by General Formula(I) below, and prodrugs, physiologically acceptable salts, hydrates, solvates thereof, methods for producing them and pharmaceutical compositions containing them: wherein A is a group represented by Formula (a) or the like: (wherein either R4 or R5 represents cyano, nitro or the like, and the other represents a hydrogen atom or the like); either R1 or R2 represents a group: -D-(X)m-R6 or the like, and the other represents a group: -E-(Y)n-R7, hydrogen atom, aryl or the like; R3 is a hydrogen atom or the like; D and E independently represent aryl; X and Y independently represent 0 or the like; R6 and R7 independently represent alkyl, aryl, arylalkyl or the like; and m and n are independently 0 or 1, provided that the aryl is optionally substituted. Such compounds exhibit a potent antagonistic activity on glucagon receptor and are of use as preventive and/or therapeutic agents for symptoms and diseases in which glucagon is involved.
