Crystalline adducts of the Lawsone molecule (2-hydroxy-1,4-naphthaquinone): optical properties and computational modelling
(Royal Society of Chemistry, 2015-09-04)Four new crystalline adducts of the Lawsone molecule (2-hydroxy-1,4-naphthaquinone) with 4,4'-bipyridine, 4-(2-pyridine-4-ethyl)pyridine, 1,3-di.4-pyridyl)propane and 2-hydroxy pyridine are reported. Adduct formation leads ... -
Hydrogen bonding networks and solid-state conversions in benzamidinium salts
(2015-07-14)Ten benzamidinium salts of carboxylic acids, amides, and sulfonamides have been crystallized from solution. Single-crystal X-ray analyses revealed various hydrogen bonding motifs which ate discussed in terms of supramolecular ... -
One-pot hydrogen peroxide and hydrohalic acid induced ring closure and selective aromatic halogenation to give new ring-fused benzimidazoles
(American Chemical Society, 2015-05-19)A new series of selectively dichlorinated and dibrominated five- to eight-membered-ring [1,2-a]-fused benzimidazoles and [1,4]oxazino[4,3-a]benzimidazoles are synthesized in mostly high yields of >80% using the reaction ... -
Synthesis of α-galactosyl ceramide analogues with an α-triazole at the anomeric carbon
(Elsevier, 2014-03-16)The synthesis of 1,2,3-triazole containing analogues of a-GalCer and galacturonic acid containing Sphingomonous cell wall antigens is described. Anomerisation was used to provide the required cc-glycosyl azide precursor. ... -
Using surface-enhanced Raman scattering (SERS) and fluorescence spectroscopy for screening yeast extracts, a complex component of cell culture media
(2012)Yeastolate or yeast extract, which are hydrolysates produced by autolysis of yeast, are often employed as a raw material in the media used for industrial mammalian cell culture. The source and quality of yeastolate can ...
