A mild, sustainable and efficient organocatalytic synthesis of thiiranes from alkenes has been developed. Starting from olefins and utilizing the epoxidation protocol developed in the Kokotos’ group, which employs 2,2,2-trifluoroacetophenone as the organocatalyst and H2O2 as the oxidant, followed by ring opening by thiourea, a variety of thiiranes were synthesized in moderate to excellent yields.
已经开发出一种温和、可持续和高效的有机催化合成硫杂丙环的烯烃。从烯烃开始,利用 Kokotos 小组开发的环氧化方案,该方案使用 2,2,2-三氟苯乙酮作为有机催化剂,H 2 O 2作为氧化剂,然后用硫脲开环,合成了多种硫杂环丙烷中等至极好的产量。
