A monomer, an organic layer composition, an organic layer, and a method of forming a pattern, the monomer being represented by the following Chemical Formula 1:
TFAA/H3PO4 mediated unprecedented N-acylation of carbazoles leading to small molecules possessing anti-proliferative activities against cancer cells
Kolli, Sunder Kumar,Prasad, Bagineni,Babu, P. Vijaya,Ashfaq, Mohd Ashraf,Ehtesham, Nasreen Z.,Raju, R. Ramesh,Pal, Manojit
supporting information, p. 6080 - 6084 (2014/08/05)
For the first time TFAA/H3PO4 has facilitated the direct and metal-free N-acylation of carbazoles leading to a number of N-acylated derivatives. Several of these compounds were found to be promising when tested for their anti-proliferative properties against oral cancer cell lines. This journal is the Partner Organisations 2014.
Palladium-catalyzed direct arylation-based domino synthesis of annulated N-heterocycles using alkenyl or (hetero)aryl 1,2-dihalides
Ackermann, Lutz,Althammer, Andreas,Mayer, Peter
experimental part, p. 3493 - 3503 (2010/02/28)
A palladium-catalyzed reaction sequence consisting of an intermolecular amination and an intramolecular direct arylation enabled highly regioselective syntheses of functionalized indoles or carbazoles and proved to be amenable to the use of inexpensive 1,2dichloroarenes as electrophiles.
Domino N-H/C-H bond activation: Palladium-catalyzed synthesis of annulated heterocycles using dichloro(hetero)arenes
Ackermann, Lutz,Althammer, Andreas
, p. 1627 - 1629 (2008/02/13)
(Chemical Equation Presented) One after the other: A novel palladium-catalyzed domino reaction consisting of an amination and a direct C-H bond arylation allows for a general synthesis of annulated heterocycles starting from readily available 1,2-dichloroarenes and primary as well as secondary anilines (see scheme; Cy = cyclohexyl). This is high-lighted by an efficient synthesis of the natural product murrayafoline A.
Recent Work on the Synthesis of 3,6-Dibenzoylcarbazole
Bonesi, Sergio Mauricio,Erra-Balsells, Rosa
, p. 1035 - 1038 (2007/10/02)
By heating carbazole (1) with aluminum trichloride and benzoyl chloride four benzoylcarbazole derivatives were obtained: N-benzoylcarbazole (2), 1-benzoylcarbazole (3), 3-benzoylcarbazole (4) and 3,6-dibenzoylcarbazole (5).The complete characterization of benzoylcarbazole derivatives 2-5 was performed by physical and spectroscopical methods (mp, tlc Rf, glc Tr, uv, ir, 1H nmr, 13C nmr and ms).
Palladium Acetate-Mediated Cyclizations of Di- and Trifunctional Triarylamines, Diaryl Ethers, and Diaryl Ketones
Hellwinkel, Dieter,Kistenmacher, Thomas
, p. 945 - 950 (2007/10/02)
Triphenylamine and its 4,(4',4")-substituted nitro or ester and methyl derivatives are cyclodehydrogenated to the corresponding carbazole derivatives 4a-d with Pd(OAc)2 in acetic acid.Further cyclizations can not be observed.Multiple cyclizations of this kind, however, can be realized with compounds of the 1,4-diphenoxybenzene (6a), 1,4-dibenzoylbenzene (6b), and 2,8-diphenoxydibenzofuran type (10), where in a very simple manner benzobisbenzofurans 8a, 9a, indenofluorene-6,12-dione (8b), 11H-fluorenobenzofuran-11-one (8c), and bisbenzofurodibenzofuran (12) become accessible.
STUDIES ON ENAMIDES PART-2 : A NOVEL PHOTOCHEMICAL SYNTHESIS OF 9H-INDOLOPHENANTHRIDIN-9-ONE, A BENZCANTHINE ANALOGUE
Ghosh, Somnath,Datta, Diptendu Bhusan,Datta, Indira,Das, Tapas Kumar
, p. 3775 - 3786 (2007/10/02)
The synthesis of 3-aroylcarbazoles and the unknown 1-aroylcarbazoles has been achieved by the photolysis of 9-aroylcarbazoles in polar solvent.Irradiation of 3(a-c) in non-polar solvent afforded regiospecifically 5(a-c), carbazole (1) and for the first time, 9H-indolophenanthridin-9-one (8) from 3b.The yield of 8 was significantly improved by UV exposure of 9-(2-iodobenzoyl)-carbazole (3e) in methanol and iodine, without providing any photomigrated product.
STUDIES ON ENAMIDES. PART- 1 : PHOTOCHEMICAL REARRANGEMENTS OF N-AROYLCARBAZOLES
Ghosh, Somnath,Das, Tapas Kumar,Datta, Diptendu Bhusan,Mehta, Sangeeta
, p. 4611 - 4614 (2007/10/02)
The synthesis of 1- and 3-aroylcarbazoles has been achieved by the photolysis of N-aroylcarbazoles alongwith the formation of carbazole and the rearranged product ratio is wavelength dependent.
