日期:——
Tetrabutylammonium fluoride (1) catalyses under mild conditions the opening of epoxides 2a-k with thiols 3-6 to produce the corresponding ß-hydroxy thioethers 7-11 in excellent yields (88-100%) and with high regioselectivity. Furthermore, O-protected glycidols react without any loss of the protective group.
四丁基氟化铵(1)在温和的条件下催化环氧化物 2a-k 与硫醇 3-6 的开环反应,生成相应的 ß- 羟基硫醚 7-11,收率极高(88%-100%),具有很高的区域选择性。此外,受 O 保护的缩水甘油在反应过程中不会损失任何保护基团。
