The title compounds are prepared by an efficient one-pot reaction involving ring-opening of an epoxide with lithium 3-trimethylsilyl-1-phenylthio-2-propyn-1-ide, tosylation of the intermediate alkoxide, and finally deprotonation. In an alternative approach, intramolecular epoxide ring opening by a ß anion is succesfully applied.
标题化合物是通过高效的一锅反应制备的,包括环氧化物与 3-三甲基硅基-1-苯硫基-2-丙炔-1-锂的开环反应、中间烷氧基的甲苯磺酰化反应以及最后的去质子化反应。另一种方法是通过 ß 阴离子成功地进行分子内环氧化物开环。
