克利贝特Chemical Name: [Cyclohexylidenebis(4,1-phenyleneoxy)]bis(2-butyl-2-carboxylic acid); 2,2'-[Cyclohexylidenebis(4,1-phenyleneoxy)]bis(2-methylbutyric acid)
CAS No. 30299-08-2
项目整合开发状态: Launched-1981
项目研究机构: Sumitomo Pharmaceuticals (Originator)
合成路线:Compound can be prepared by several different ways:1) By condensation of cyclohexylidenebis(4-hydroxyphenyl) (I) with 2-butanone (A) and CHCl3 by means of NaOH or KOH at 50-150 C.2) By alkylation of cyclohexylidenebis(4,1-phenyleneoxy)bis(2-butanoic acid) diethyl ester (III) with NaH and methyl iodide in DMF to give the ester (IV),which is then hydrolyzed with K2CO3 in methanol.3) By oxidation of cyclohexylidenebis(4,1-phenyleneoxy)bis(2-oxo-3-methyl-3-pentyl) (II) with sodium hypobromite or potassium hypochlorite in dioxane - water.
