Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. 82911-69-1, Name is N-(9-Fluorenylmethoxycarbonyloxy)succinimide, belongs to thiazines compound, is a common compound. In a pantent, author is Gagarin, Aleksey A., once mentioned the new application about 82911-69-1, SDS of cas: 82911-69-1.
Two Approaches for the Synthesis of Fused Dihydropyridines via a 1,6-Electrocyclic Reaction: Fluorescent Properties and Prospects for Application
Reactions of penta-2,4-dienethioamides with acetylenedicarboxylic acid, methyl and ethyl esters, and methyl propiolate were systematically studied, and a number of new 2,3-dihydro-5H-thiazolo-[3,2-a]pyridines (DTPs) and 4H,6H-pyrido[2,1-b][1,3]thiazines (PTZs) were prepared. A possible mechanism for a multistep domino transformation is suggested, and the key step is the 1,6-electrocyclic reaction. An additional alternative method for the synthesis of new heterocyclic systems was achieved. Evidence of the electrocyclic mechanism of a key step was collected from the analysis of the spatial structure of the synthesized bicyclic nonaromatic pyridines by X-ray diffraction and quantum chemical calculations, as well as from the thermodynamic quantities. DTPs exhibited yellow fluorescence in solution and yellow to red emissions in the solid state. Biological investigations demonstrated the ability of DTPs to penetrate living and fixed cells and presumably accumulate in lysosomes.
SDS of cas: 82911-69-1, The π-electrons of these planar compounds are free to cycle around the circular arrangements of atoms found in the aromatic moieties. This stems from the resonance found in planar ring systems, like benzene, and 82911-69-1.
