چکیده
We report a new synthetic route to 5,11-disubstituted indeno[1,2-b]fluorene-6,12-diones that is amenable to larger scale reactions, allowing for the preparation of gram amounts of material. With this new methodology, we explored the effects on crystal packing morphology for the indeno[1,2-b]fluorene-6,12-diones by varying the substituents on the silylethynyl groups.

Molecular Modeling of indeno [1,2-b] quinoline-9,11-diones as cytotoxic agents
Deoxyribonucleic acid (DNA) is an important molecular target for anti-cancer agents due to its involvement in gene expression and protein synthesis which are fundamental steps in cell division and growth. A number of antineoplastic agents interfere with DNA and hence disturb the cell cycle. Compounds including planar aromatic rings are privileged scaffolds in binding to the DNA. This characteri...

A series of novel indeno[1, 2-b]quinoxalin-11-ylidenamines 2-9 have been synthesized via condensation of indane[1, 2-b]quinoxalin-11-one (1) with various primary aromatic amines in presence of AcOH for 3 h. Compound 1 was synthesized by condensation of indane-1,2,3-trione with benzene-1,2-diamine in presence of AcOH. The synthesized compounds were characterized by IR, 1H-NMR, ...

Hexakis(4-methoxyphenyl)benzene (HPB-OMe(1)) and hexakis(2,6-dimethyl-4-methoxyphenyl)benzene (HPB-OMe(2)) were synthesized via organometallic complex catalysis. The treatment of HPB-OMe(1) with FeCl3 caused cyclodehydrogenation at two positions to yield an oligophenylene with an indeno[1,2-b]fluorene structure (IF-OMe). Deprotection of the methoxy groups of these compounds was conducted by tre...
