A series of new fluorene bisamide derivatives were synthesized through multi-component Ugi reaction and tested for their in vitro anti-mycobacterial activity. The structures of the products 5a-w were deduced from their IR, 1H NMR, and 13C NMR spectra. Elemental analyses (CHN) for novel compounds (5a, 5d, 5f, 5h, 5k, 5l, 5p, 5s, 5t, 5v, 5w) was done to. These compounds were evaluated as anti-bac...

We report the synthesis of both macrocyclic and linear derivatives of pyrrole-2,5-diacetic bisamides, and the studies of their anion binding properties, which are further compared with the properties of similar derivatives bearing dipicolinic or isophthalic moieties. The new macrocyclic compound built on pyrrole-2,5-diacetic bisamide was found to be an efficient receptor for H2PO4 and PhCOO , e...

The emissions of gasoline and diesel engines contribute significantly to ever increasing pollution of living environment. A specific part of exhaust gases is composed of carcinogenic derivatives of polycyclic aromatic hydrocarbons. Amino derivatives of parent hydrocarbon fluorene, namely 2-aminofluorene (2-AF) and 2,7-diaminofluorene (2,7-DAF), are well-known hazardous air and water pollutants ...

The structures of two derivatives of the bisdioxine diisocyanate 1, the bisurea 4 and the biscarbamate 5, are established by X-ray crystallography and DFT calculations. These compounds possess endo,endo structures, in the case of the bisurea 4 with two nearly parallel pendant chains. The X-ray structures are reproduced very well by DFT calculations. Similar endo,endo conformations are calculate...

The reactivity of fluorene, anthracene and fluoranthene under oxidation and reduction conditions has been investigated in this study. This project looks at catalytic and green approaches of converting PAH to less toxic and/or less stable derivatives that are amenable to further degradation. Hydrothermal reactions have been performed at 300 C with pure H2O and Nafion-SiO2 catalyst for oxidation,...

Abstract Fluorene and fluorenone are privileged structures with extensive utility in both materials science drug discovery. Here, we describe syntheses of those moieties through isocyanide-based multicomponent reactions (IMCRs) the incorporation products diverse complex derivatives that can be further utilized. We performed six different IMCRs, based on dual functionality 9-isocyano-9H-fluorene...
