densely functionalized epoxy sulfinyl tetrahydrofurans, based on the unexpected and highly stereoselective remote nucleophilic epoxidation of hydroxy 1-sulfinyl butadienes with t-BuOOK, followed by ring closure and subsequent epoxidation of the resulting sulfinyl dihydrofurans, is described. Alternatively, the treatment of these dienes with m-CPBA followed by acid-catalyzed cyclization gives rise to related
描述了一种新的对映纯致密化官能化的环氧亚磺酰基四氢呋喃的方法,该方法基于羟基1-亚磺酰基丁二烯与t-BuOOK的出乎意料且高度立体选择性的远程亲核环氧化,然后闭环并随后将生成的亚磺酰基二氢呋喃进行环氧化。或者,用间-CPBA处理这些二烯,然后进行酸催化的环化反应,可以高产率但低选择性地产生相关的磺酰基二氢呋喃。还研究了这些底物的亲核环氧化的立体化学结果。
