Abstract

magnified image

3‐Thioformylindolizines undergo novel reductive coupling reaction in the presence of tributylphosphine to give E‐1,2‐bis(3‐indolizinyl)ethylenes in high yield. These reactions proceed via (3‐indolizinyl)methylene carbene intermediate and provide a new, stereoselective synthesis of the bis(3‐indolizinyl)ethylene derivatives highly.
