Synthesis of di(Imdazolium) and di(Pyrazolium) Salts as Precursors for N-heterocyclic Dicarbene Complexes [PDF]

open access: yes, 2001
Alpha,omega-bis(pyrazol-1-yl)alkanes and alpha,omega-bis(imidazol-1-yl)alkanes with spacers consisting of four to ten methylene groups have been prepared from pyrazole, 3,5-dimethylpyrazole or imidazole and corresponding dibromoalkanes in a superbasic ...

Studies with Arylhydrazono-3-oxopropanals:A novel route to synthesis of substituted pyrazoles, oxoalkanonitrile and glyoxalonitrile containing sulfa drug moieties [PDF]

open access: yes, 2008
Coupling of enaminones 1 with diazonium salts gave thehydrazonopropanals 3a-h. Compound 3 react with ω-bromoacetophenone or α-chloroacetanilide to yield 5 and 8. These compounds were cyclized smoothly into 6 and 9 respectively.

Synthesis and biological evaluation of tetrahydropyridinepyrazoles ('PFPs') as inhibitors of STAT3 phosphorylation [PDF]

open access: yes, 2013
The transcription factor STAT3 is constitutively overexpressed in many human tumors and hence represents a putative target for anticancer drug design. In this work, we describe the synthesis and biological evaluation of a novel chemotype, pyridine-fused ...
