High regio- and stereo-selective introduction of a trifluoromethyl group in various unsaturatedsystems is described. The key step is the treatment of 1,1-difluoro-1-alken-3-olswith (diethylamino)sulphur trifluoride (DAST) to give 1,1,1-trifluoro-2-alkenes.
描述了在各种不饱和系统中对三氟甲基的高区域和立体选择性引入。关键步骤是用(二乙基氨基)三氟化硫(DAST)处理1,1-二氟-1-烯烃-3-醇,得到1,1,1-三氟-2-烯烃。
