Efficient one-pot four-component sequential synthesis of 5-acetyl-4-amino-3-(aryl)thieno[2,3-b]pyridin-6(7H)-ones in the presence of aluminum chloride
A simple and efficient procedure for the synthesis of 5-acetyl-4-amino-3-(aryl)thieno[2,3-b]pyridin-6(7H)-ones by one-pot two-step reaction between 2-(1-arylethylidene)malononitriles, elemental sulfur, and Meldrum's acid in the presence of AlCl3 (15 mol %) in 1,2-dichloroethane under refluxing conditions is reported.
期刊介绍:
Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry.
Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters.
Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
