鉮盐1以碳酸钾为碱分别与含对三氟甲基苯基及双吸电子基团的烯烃23反应, 高产率、高立体选择性地合成了含对三氟甲基苯基的顺-1,2-环丙烷衍生物4或顺-2,3-二氢呋喃衍生物5, 并对其产物结构进行了确证.

关键词: 胂叶立德, 环丙烷衍生物, 二氢呋喃衍生物, 立体选择性

Arsonium bromides 1 were reacted with electron-deficient olefins containing one p-trifluoromethylphenyl and two other electron withdrawing groups 2 or 3 in the presence of K2CO3 to form cis-1,2-cyclopropane or cis-2,3-dihydrofuran derivatives containing the p-trifluoromethylphenyl group 4 or 5 in high yields with high stereoselectivity. The structures of these products were confirmed by 1H NMR, 13C NMR, IR, MS and HRMS spectra.

Key words: cyclopropane, dihydrofuran, stereoselectivity, arsenic ylide
