摘要
New C-4 thiazole 4, 5 and aminothiazole 6, 7 kainoid analogues were efficiently synthesised in five steps from commercially available (-)-alpha-kainic acid 1 and exhibited strong binding to the kainate receptors. A reactive alpha-bromoketone 10 was generated and reacted with thioamides and thioureas to form thiazole and aminothiazole heterocycles 11-14. Deprotection gave the new kainoid amino acids 4-7 in excellent yield. (C) 2000 Elsevier Science Ltd. All rights reserved.
