SELENIUM HETEROCYCLE XL II [1]. SYNTHESES OF SUBSTITUTED THIAZOLO, SELENAZOLO AND 1,2,3-SELENADIAZOLOINDOLES
Authors: not saved
Abstract:
Reaction of compound 1 with thiobenzarnide or substituted selenobenzamides afforded substituted pyrrolobenzothiazole or selenazoles (2) respectively. Selenium dioxide oxidation of the semicarbazone 4 with selenium dioxide gave 6- benzenesulfonyl- 4,5-dihydro-pynolo [3,2-el benzoselenadiazole (5).

Starting from readily available 2-substituted-4-methylthiazole-5-carboxylic acid hydrazide (1), The title compounds were prepared. The reaction of compound 1 (R=CH3) with formic acid yielded 1-(formyl)-2-(2,4-dimethylthiazole-5-carboxyl) hydrazine (2). Refluxing the latter with phosphorous pentasulfide in xylene afforded compound 3, the reaction of compound 2 with phosphorous pen...

full textA Universal Isocyanide for Diverse Heterocycle Syntheses
Novel scaffolds are of uttermost importance for the discovery of functional material. Three different heterocyclic scaffolds easily accessible from isocyanoacetaldehyde dimethylacetal 1 by multicomponent reaction (MCR) are described. They can be efficiently synthesized by a Ugi tetrazole multicomponent reaction of 1. We discuss the synthesis, 3D structures, and other physicochemical properties.

The reaction of P-diketones 1 with phenyl hydrazine afforded 5-aryl-3-(1- methyl-5-nitro-2-imidazoly1)-1-phenylpyrazole (2) and 3-aryl-5-(1-methyl-5- nitro-2-imidazoly1) -1-phenylpyrazole (3). The reaction of diketones (1) with urea in the presence of p-toluenesulfonic acid gave 4-(or 6-)aryl-6-(or 4-)(1-methyl- 5-nitro-2-imidazolyl)-1-(lH)pyrimidones (4). The structures of all compounds w...

The syntheses, photophysical properties and in vitro biological behavior of a series of nine Zn((II))-phthalocyanines (ZnPcs) bearing one to eight positively-charged trimethylaminophenoxy groups are reported. All ZnPcs are highly soluble in polar organic solvents, and show fluorescence and singlet oxygen quantum yields in the ranges 0.11-0.21 and 0.16-0.47, respectively. The cytotoxicity of the...
