Abstract
AbstractAn efficient dirhodium(II)‐catalyzed macrocyclization reaction of alkyne‐containing diazoacetates through intramolecular metal carbene cyclopropanation is described. This method provides a variety of 12‐ to 22‐membered macrocyclic alkynes, which incorporate ortho‐aryl, cyclopropane, and cyclopropene units, in good to excellent yields under mild reaction conditions.magnified image
