Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ARYLACETYLENES -- MICROWAVE RADIATION -- IONIC LIQUID Аннотация: The reaction of 5-(het)aryl-1-ethyl-2(1H)-pyrazinones with terminal arylacetylenes, leading to a mixture of two isomeric 4-aryl- and 5-aryl-substituted 2(1H)-pyridones has been investigated. The regioselectivity of this reaction has been shown on the basis of reaction mixtures study by chromato-mass spectrometry. A crystallographic investigation of the synthesized 2(1H)-pyridones and also a forecast of their potential biological activity have been carried out \\\\Expert2\\nbo\\Chemistry of Heterocyclic Compounds\\2011, v.47, N 6, p.710-718.pdf |
