Hydroxocobalamin, also known as vitamin B 12a and hydroxycobalamin, is a vitamin found in food and used as a dietary supplement. [1] As a supplement it is used to treat vitamin B12 deficiency including pernicious anemia.
This synthesis of vitamin B 12 is of no practical consequence due to its length, taking 72 chemical steps and giving an overall chemical yield well under 0.01%. [140] Although there have been sporadic synthetic efforts since 1972, [ 139 ] the Eschenmoser–Woodward synthesis remains the only completed (formal) total synthesis.
The structure of vitamin B 12 was the first low-molecular weight natural product determined by x-ray analysis rather than by chemical degradation. Thus, while the structure of this novel type of complex biomolecule was established, its chemistry remained essentially unknown; exploration of this chemistry became one of the tasks of the vitamin's chemical synthesis.
