Sulfoxonium ylides as carbene precursors couple smoothly with thioureas in the presence of 5 mol% of rhodium(II) acetate dimmer via carbenoid insertion to afford the corresponding 2-aminothiazoles with high chemoselectivity, providing a facile and efficient approach to access a variety of 2-aminothiazole derivatives with good functional groups tolerance.
在 5 mol% 的乙酸铑(II)二聚体的存在下,作为卡宾前体的磺基叶立德通过卡宾插入提供了相应的具有高化学选择性的 2-氨基噻唑,提供了一种简单有效的方法来获得各种 2-具有良好官能团耐受性的氨基噻唑衍生物。
