Among the intramolecular cyclodehydration of 2-(β-, δ-, and e-aminoalkyl)oxazoles, 2-(δ-aminoalkyl)oxazoles afforded the desired 1,2-tetramethyleneimidazoles on pyrolysis, while 2-(β- and e-aminoalkyl)oxazoles unchanged under the same conditions.
在 2-(β-、δ-和 e-氨基烷基)恶唑的分子内环化脱水反应中,2-(δ-氨基烷基)恶唑通过热解得到所需的 1,2-四亚甲基咪唑,而 2-(β-和 e-氨基烷基) )恶唑在相同条件下不变。
