One-pot Fischer indolisation indole N-alkylation enables straightforward, rapid synthesis of structurally-diverse 1,2,3-trisubstituted indoles from simple, widely-available precursors.

Urocanic acid (UCA) derivatives were tested for their anti-inflammatory activity in inflammatory bowel disease (IBD) in two models: ex vivo and an experimental mouse model. Ex vivo: inflamed colonic tissue was incubated in culture medium with or without the UCA derivatives. Biopsies, incubated with UCA derivatives, produced lower levels of proinflammatory cytokines IL-6 and IL-8 as compared to ...

the reaction of p-diketones 1 with phenyl hydrazine afforded 5-aryl-3-(1- methyl-5-nitro-2-imidazoly1)-1-phenylpyrazole (2) and 3-aryl-5-(1-methyl-5- nitro-2-imidazoly1) -1-phenylpyrazole (3). the reaction of diketones (1) with urea in the presence of p-toluenesulfonic acid gave 4-(or 6-)aryl-6-(or 4-)(1-methyl- 5-nitro-2-imidazolyl)-1-(lh)pyrimidones (4). the structures of all compounds were c...

C–H olefination of alkynes has been realized as an efficient approach to access axially chiral trisubstituted olefins, where two classes arenes have identified.

Vulvo-vaginal candidiasis (VVC) is a common infection among women. 5-8% of women with acute infection experience recurrent vulvo-vaginal candidiasis (RVVC). There is currently no gold standard treatment for RVVC. Although antifungal agents such as imidazoles have been successfully used as first-line treatment for acute VVC, the effectiveness of these medications is limited for RVVC, and various...

3- And 9-component Pd(0) catalysed assembly of allenes, aryl iodides and N-nucleophiles with concomitant installation of trisubstituted Z-alkenes is readily achieved.

The stereospecific and regioselective C(3) alkynylation of trisubstituted epoxides has been achieved with lithium alkynyl trimethylaluminium ate complexes in the presence of BF3 x OEt2.

A variety of 1,1,2-trisubstituted-1H-indenes are synthesized by the reaction of aliphatic ketones, aryl-substituted alkynes and NbCl3(DME) in 1,2-dichloroethane under reflux conditions.
