Synthesis and Anti-Mycobacterium tuberculosis Evaluation of Aza-Stilbene Derivatives
(Hindawi Publishing Corporation, 2011-01-01)
Tuberculosis (TB) is a truly global disease, found in every country on earth. One-third of humanity, over 2 billion people, carry the bacillus that causes TB and 2 million people die of the disease each year. Despite that, ...

Ultrasound-assisted synthesis of Z and E stilbenes by Suzuki cross-coupling reactions of organotellurides with potassium organotrifluoroborate salts
(Elsevier B.V., 2006-06-12)
Palladium (0)-catalyzed cross-coupling reactions between potassium aryl- and vinyltrifluoroborate salts and aryl- and vinylic tellurides proceeds readily to afford the desired stilbenes in good to excellent yields. Stilbenes ...
Synthesis and biological evaluation of cytotoxic properties of stilbene-based resveratrol analogs
(Elsevier France-editions Scientifiques Medicales ElsevierParisFrança, 2009)
Room-Temperature and Transition-Metal-Free Mizoroki Heck-type Reaction. Synthesis of E-Stilbenes by Photoinduced C-H Functionalization
(American Chemical Society, 2014-01)
We report a conceptually different approach toward E-stilbene syntheses by photoinduced direct C-H arylation of alkenes at rt without the addition of transition metals, with a broad range of aryl halides, including ArI, ...
Configuration of stilbene derivatives by (1)H NMR and theoretical calculation of chemical shifts
(ELSEVIER SCIENCE BV, 2010)
The direct E/Z configuration assignment of tri- and tetra-substituted stilbenes (and other analogous olefins) when only one of the isomers is available is a quite challenging task. Sometimes, a chemical transformation or ...
SYNTHESIS AND CHARACTERIZATION OF NEW LIQUID-CRYSTALLINE DYES FOR NONLINEAR OPTICS
(TAYLOR & FRANCIS LTD, 1993)
We present the synthesis and a description of the physical properties of several organic dyes containing stilbene as well as azomethine groups. The preparations of all compounds started from a common precursor, ...
