  名称：

  Novel and efficient synthesis of 4,7-dihydro-1H-pyrrolo[2,3-b]pyridine derivatives via one-pot, three-component approach from N-substituted 5-amino-3-cyanopyrroles, various carbonyl and active methylene compounds

  摘要：

  An efficient route to novel 4,7-dihydro-1H-pyrrolo[2,3-b]pyridines with incorporated tetrahedral fragment in the position-4 via three-component reaction of N-substituted 5-amino-3-cyanopyrroles, various carbonyl and active methylene compounds has been developed. In the same time, by using developed methods here, the 4,7-dihydro-1H-pyrrolo[2,3-b]pyridines with fused 4-spiro-frameworks were synthesized starting from isatins and a set of 1,2-dicarbonyl compounds. The reactions were carried out under mild conditions using ethanol, acetic acid or 1,4-dioxane as solvent. (C) 2013 Elsevier Ltd. All rights reserved.
