Two new cobalt corrinoid intermediates, cobalt-precorrin 5A and cobalt-precorrin 5B, have been synthesized with the aid of overexpressed enzymes of the vitamin B(12) pathway of Salmonella entericaserovar typhimurium. These compounds were made in several regioselectively (13)C-labeled forms, and their structures have been established by multidimensional NMR spectroscopy. The addition of CbiF to the
