Заглавие : Unexpected formation of diethyl 2-ethoxy-6-CF.sub.3-2H-pyran-3,5-dicarboxylate from the condensation of ethyl 4,4,4-trifluoroacetoacetate with CH(OEt).sub.3 Место публикации : Tetrahedron Letters. - 2017. - Vol. 58, № 8. - С. 744-747 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): pyran-- detrifluoroacetylation--ethyl trifluoroacetoacetate--condensation--pyridines Аннотация: The one-step preparation of diethyl 2-ethoxy-6-CF3-2H-pyran-3,5-dicarboxylate via the condensation of ethyl 4,4,4-trifluoroacetoacetate with CH(OEt)3 has been reported and a plausible mechanism for this transformation is discussed. To demonstrate the synthetic potential of the obtained pyran, the reactions with ammonia and aromatic amines to give trifluoromethylated pyridine derivatives are presented.
