Haem d1: Stereoselective synthesis of the macrocycle to establish its absolute configuration as 2R,7R

Although the gross structure of haem d1 1 has been established, the absolute stereochemistry at C-2 and C-7 is unknown. An unambiguous stereoselective synthesis of the ester of the metal-free macrocycle corresponding to haem d1 has b
