Bis-diazo,triaryl and aryldiazo-N-arylphenazonium quencher moieties, substituted with electron-withdrawing and electron-donating substituents which induce polarity in the delocalized aryl/diazo ring systems, are useful as labels when attached to biomolecules such as polynucleotides, nucleosides, nucleotides, and polypeptides. The quencher moieties are non-fluorescent and accept energy from fluorescent reporter labels by any energy-transfer mechanism, such as FRET.
Fluorescence quencher compositions are useful in preparing quencher labelled biomolecules for various molecular biology assays based on fluorescence detection.

Design, synthesis, and optical resolution of a novel non-natural chiral auxiliary, 1-(2,5-dimethoxyphenyl)ethylamine. Application to diastereoselective alkylation of aldimines
A chiral amine, 1-(2,5-dimethoxyphenyl)ethylamine, was found to be an effective chiralauxiliary for the diastereoselective alkylation of its aldimines with alkylmetals. The 1-(2,5-dimethoxyphenyl)ethyl group of the chiralauxiliary could be removed by the acetylation and then oxidation of the resultant alkylated product, accompanying an amino-transfer from the chiralauxiliary to the final product
The invention relates to novel 1,2,3,4-tetrahydroisochinoline derivatives of formula (I) and their use as active ingredients in the preparation of pharmaceutical compositions. The invention also concerns related aspects including processes for the preparation of the compounds, pharmaceutical compositions containing one or more of those compounds and especially their use as orexin receptor antagonists.
