A novel efficient and eco-friendly method for the synthesis of 2-trichloromethyl-4-vinyloxazoline is presented that involves Lewis acid-catalyzed cyclization of bisimidate derived from but-3-ene-1,2-diol. The derivatization potential of 2-trichloromethyl-4-vinyloxazoline is demonstrated by ring opening reactions with water, hydrobromic acid, hydrochloric acid, and acetic acid leading to allylamine
提出了一种新颖有效的环保方法,用于合成2-三氯甲基-4-乙烯基恶唑啉,该方法涉及路易斯酸催化的衍生自丁-3-烯-1,2-二醇的双亚氨酸酯的环化反应。通过与水,氢溴酸,盐酸和乙酸发生开环反应生成烯丙胺衍生物,证明了2-三氯甲基-4-乙烯基恶唑啉的衍生化潜力。
