摘要:

研究了三氟化硼乙醚(BF3·OEt2)催化2-(N-取代氨基甲酰基甲基氨基)苯甲醇与醛的反应,发展了合成取代3,1-苯并噁嗪类化合物的方法,通过该方法合成了一系列新型结构的1-(氨基甲酰基甲基)-2-烃基-3,1-苯并噁嗪类化合物。 对于这类反应BF3·OEt2比三甲基氯硅烷(TMSCl)和四氯化锡(SnCl4)的普适性更广,它能有效催化这类反应,而后二者却不能。 探讨了TMSCl和SnCl4不能催化2-(N-取代氨基甲酰甲基氨基)苯甲醇与醛反应的原因。

Abstract:

Boron trifluoride diethyl etherate(BF3·OEt2)catalyzed reaction of 2-(N-substituted amino)benzyl alcohol with aldehyde was studied, and resulted a new method for the preparation of substituted 3,1-benzoxazine. By this method, a series of novel 1-(carbamoylmethyl)-2-aryl/alkyl-3,1-benzoxazines was prepared. It was found that BF3·OEt2 was a more general catalyst for these reactions than chlorotrimethylsilane and SnCl4 for the reaction and the reason causing this difference was discussed.

Key words: nitrogen heterocycles, substituted 3,1-benzoxazines, synthesis, boron trifluoride diethyl etherate, catalyst
