Asymmetric construction of substituted pyrrolidines via 1,3-dipolar cycloaddition of azomethine ylides and chiral acrylates derived from biomass
(ElsevierAmsterdam, 2014-04)
The first application of chiral auxiliaries synthesized from levoglucosenone (a biomass-derived anhydrosugar) in asymmetric 1,3-dipolar cycloaddition reactions of azomethine ylides is herein reported. The corresponding ...
Conformational constraint in ferroelectric liquid crystals incorporating a pyrrolidine-type ring: FLC materials comprising parallel dipolar moments
(2007)
Ferroelectric liquid crystals bearing a chiral pyrrolidine-type ring were prepared using (-)-(S)-malic acid as a building block. The compounds were characterized using the thermal analysis techniques of DSC and POM, ...
Participation of transcription factors from the Rel/NF-κB family in the circadian system in hamsters
(Elsevier Ireland, 2004-03)
We have studied the presence and activity of components of the nuclear factor-κB (NF-κB) transcription factor in the hamster circadian system analyzing wheel-running activity, protein expression and DNA binding activity ...
