Abstract Seven novel chiral C2-symmetric substituted bisoxazoline ligands containing 2,5-di(m-substituted)phenyl-1,3,4-oxadiazole have been synthesized from 2,5-di-(m-carboxylphenyl)-1,3,4-oxadiazole and aminoalcohol by NaOH or Et3N cyclization method via halogenated amide intermediate.
摘要 由 2,5-二-(间-羧基苯基)-1,3 合成了七个含有 2,5-二(间-取代)苯基-1,3,4-恶二唑的新型手性 C2-对称取代双恶唑啉配体, 4-恶二唑和氨基醇通过NaOH或Et3N环化方法通过卤代酰胺中间体。
