On December 7, 2000, Davenport, Adam J.; Davies, David L.; Fawcett, John; Garratt, Shaun A.; Russell, David R. published an article.Quality Control of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine The title of the article was Arene ruthenium complexes with pyridyloxazolines: synthesis and applications as asymmetric catalysts for Diels-Alder reactions. And the article contained the following:
Reaction of the dimers [RuCl2(arene)]2 (arene = mesitylene, p-cymene, benzene, C6Me6) with pyridyloxazolines (pymox) gave complexes [RuCl(pymox)(arene)][SbF6] which have been fully characterized. Using chiral ligands diastereomers are formed, the diastereoselectivity depending on the substituents on the arene and on the oxazoline. The complexes [RuCl(Me2-pymox)(mes)][SbF6], [RuCl(Ph-pymox)(mes)][SbF6], [RuCl(iPr-pymox)(mes)][SbF6] and [RuCl(indanyl-pymox)(mes)][SbF6] (mes = mesitylene) have been characterized by x-ray crystallog. Treatment of these cations with AgSbF6 generates dications which in some cases can be isolated as aqua species [Ru(OH2)(pymox)(arene)]2+; these dications are enantioselective catalysts for Diels-Alder reactions of acroleins and dienes; a mechanism is proposed which accounts for the observed enantioselectivity. The experimental process involved the reaction of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine(cas: 109660-12-0).Quality Control of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine
