Design, synthesis and biological studies of a library of NK1-Receptor Ligands Based on a 5-arylthiosubstituted 2-amino-4,6-diaryl-3-cyano-4H-pyran core: Switch from antagonist to agonist effect by chemical modification
(Elsevier, 2017)
A library of 5-arylthiosubstituted 2-amino-4,6-diaryl-3-cyano-4H-pyrans has been synthesized as a new family of non-peptide NK1 receptor ligands by a one-pot cascade process. Their biological effects via interaction with ...

3-(Piperidin-1-ium-1-yl)-6-azoniaspiro[5.5]undecane dibromide monohydrate
(International Union of Crystallography, 2011)
The title compound, C15H30N2 2+·2Br−·H2O, was synthesized by reaction of 4-piperidinopiperidine with dibromopentane. The dication is built up from three linked piperidine rings, two of which have one quaternary N atom ...

Nickel and Palladium Complexes with New Phosphinito-Imine Ligands and Their Application as Ethylene Oligomerization Catalysts
(American Chemical Society, 2012)
Phosphinito-imines, a new class of P,N donors, are readily generated by reaction of bulky arylamide anions [R2CONAr]− (R2 = Me or t-Bu; Ar = 2,6-i-Pr2C6H4) with chlorophosphines ClP(R1)2. In solution, free phosphinito-imines ...

Dibenzyl and diallyl 2,6-bisiminopyridinezinc (ii) complexes: Selective alkyl migration to the pyridine ring leads to remarkably stable dihydropyridinates
(Royal Society of Chemistry, 2013)
Diorganozinc compounds (ZnR2) with R = CH2Ph or CH2CH[double bond, length as m-dash]CH2 react with 2,6-bisiminopyridines (iPrBIP) to afford thermally stable dihydropyridinate(−1) complexes, and do not react if R = CH2SiMe3 ...

Ruthenium(II) Complexes Containing Lutidine-derived Pincer CNC Ligands: Synthesis, Structure and Catalytic Hydrogenation of C=N bonds
(Wiley-Blackwell, 2015)
A series of Ru complexes containing lutidine‐derived pincer CNC ligands have been prepared by transmetalation with the corresponding silver‐carbene derivatives. Characterization of these derivatives shows both mer and fac ...
