The chemoselective epoxidation of electron-deficient olefins in the presence of electron-rich alkene moieties is reported. This chemoselective epoxidation strategy undergoes a conjugated olefinepoxidation and BHT hydroxylation process to give various useful oxiranes in high yields, especially for the 2-substituted 2-trifluoromethyloxiranes. Importantly, this protocol features mild conditions, is transition-metal
