catalysis of copper, 2-aminophenols or 2-aminothiophenols reacted with thiocarbamoyl chlorides via a tandem manner, furnishing a series of 17 benzoheterocycles smoothly with good to excellent yields (70–91%). The broad substrate scope, short reaction time, mild react conditions, easy performance and nice yields make this approach attractive, showing its practical synthetic value for the preparation of some
提出了用于制备取代的2-氨基苯并恶唑和2-氨基苯并噻唑的有用方案。在铜的催化下,2-氨基苯酚或2-氨基硫代苯酚与硫代氨基甲酰氯通过串联方式反应,可顺利提供一系列17个苯并杂环,并具有良好或优异的收率(70-91%)。广泛的底物范围,短的反应时间,温和的反应条件,容易的操作和良好的收率使该方法具有吸引力,显示出其对某些生物或药物活性化合物的制备的实用合成价值。
