n-Octyl-3-methylpipyridinium bromide ([OMePPy]+Br-): novel ionic liquid to promote green synthesis of polycyclic fused acridines

In this research, various polycyclic fused acridines were synthesized via the highly efficient and green one-step four-component reaction between isatins, dimedone, various amines, and dimethylacetylenedicarboxylates (DMAD/DEAD) in the presence of n-octyl-3-methylpipyridinium bromide ([OMePPy]+Br-) as a newly prepared ionic liquid, in absolute green situations at room temperature under solvent-...

A periodic table for polycyclic aromatic hydrocarbons. Isomer enumeration of fused polycyclic aromatic hydrocarbons. Part I

a few people, however, who recognize a need to use the system but, for reasons of their own, choose to have a search intermediary do it for them or at least work with them on a graphical search session. At this point, therefore, it appears that the role of the search specialist has evolved away from searches originated by individual users (except in a few cases) who now can and should run their...

Application of Thionine Dye for Highly Sensitive and Selective Catalytic kinetic Determination of Osmium

Anew, highly sensitive and selective catalytic kinetic method (CKM) for determination of osmium (VIII) has been established based on its catalytic effect on the oxidation of thionine dye by hydrogen peroxide in alkaline medium. The reaction has been followed spectrophotometrically by measuring the decrease in the absorbance band of thionine at 600 nm. Under the optimum conditions, the proposed ...

One-pot synthesis of polycyclic nucleosides with unusual molecular skeletons.

An alpha hydroxy pyrrolidine tricyclic nucleoside 3 and its spontaneous reaction with acetone is described. In this transformation highly functionalized polycyclic nucleosides with rather unusual molecular skeletons are formed in a complete regio- and stereoselective way. The reaction involves the formation of three new bonds, two of them novel carbon-carbon bonds, in a one-pot way. An enamine-...
