- ... The synthesis of vitamin B₁₂ derivatives for selective orthogonal conjugation at both the Co center and 5′-OH is reported. Newly developed, reduction-free, direct alkynylation of vitamin B₁₂ at the central cobalt ion proved to be versatile, with the formed acetylides, unlike other metalloorganic derivatives, showing remarkable heat and light stability, thus making them promising candidates as a dr ...
