The intramolecular addition of a diazo ester group to a triple bond in the presence of chiral dirhodium(II) carboxamidate catalysts gives macrocyclic lactones with a fused cycloproprene ring [Eq. (a)]. This efficient reaction is characterized by high enantiocontrol (up to 98% ee) and chemoselectivity.
