Synthesis of functionalized hydroxy-thiophene motifs as amido- and sulfonamido-phenol bioisosteres
摘要:
Novel highly substituted hydroxy thiophene motifs were designed and synthesized as viable amido phenol and sulfonamido phenol bioisosteres. Hydroxy group-directed regioselective bromination and palladium-catalyzed amination of thienyl bromide via Buckwald protocol are the key elements of the synthetic approach. The hydroxy thiophene-containing compounds displayed good binding inhibitions. (C) 2009 Elsevier Ltd. All rights reserved.
