摘要: The Friedel–Crafts acylation of alkynes stereoselectively provides (Z)-β-chlorovinyl ketones, whereas the AlCl3-promoted reaction yields a mixture stereoisomeric β-chlorovinyl ketones. To develop (E)-selective synthesis flow chemistry approach was devised for that defies facile (E) → (Z) isomerization under conditions. Compared to batch reactions, fast, clean, high yielding, and stereoselective synthetic route (E)-β-chlorovinyl
