Cyclopropanation of trifluoromethyl(sulfinyl, sulfonyl) ethylenes was achieved by utilization of α-bromo- or α,α-dibromo 1,3-dicarbonyl compounds in the presence of bases. DBU was found to be the best choice to get good yields of cyclopropanes with CF3S(O)n (n = 1, 2) groups. First representatives of the cyclopropanes bearing trifluoromethylsulfinyl group were synthesized.
三氟甲基(亚磺酰基,磺酰基)乙烯的环丙烷化是通过在碱的存在下利用α-溴-或α,α-二溴1,3-二羰基化合物实现的。发现DBU是获得CF 3 S(O)n(n = 1,2)基团的环丙烷良好收率的最佳选择。合成了带有三氟甲基亚磺酰基的环丙烷的首个代表。
