Ciclopirox olamine, HOE-296, Ciclochem, Penlac nail lacquer, Mycoster, Batrafen, Loprox

环吡酮胺 环吡酮胺 Chemical Name: 6-Cyclohexyl-1-hydroxy-4-methyl-2(1H)-pyridinone 2-aminoethanol
CAS No. 41621-49-2, 29342-05-0 (free base)
项目整合开发状态: Launched-1982
项目研究机构: Aventis Pharma (Originator), Pierre Fabre (Not Determined), Ferrer (Licensee)
合成路线:Compound can be prepared in two different ways:1) The reaction of methyl 5-oxo-5-cyclohexyl-3-methylpentenoate (I) with NH2OH gives the corresponding oxime (II),which is then cyclized to 6-cyclohexyl-1-hydroxy-4-methyl-2(1H)-pyridone (III).Finally,this compound is salified with ethanolamine (IV).2) Compound (III) can also be obtained by reaction of 6-cyclohexyl-4-methyl-2-pyron (V) with hydroxylamine hydrochloride in hot 2-aminopyridine.
