Vitamin B12 and its derivatives present excellent paradigms for bioinspired catalysis. The inherent challenges for derivatizing cobalamins, such as vitamin B12 , to incorporate them in supramolecular designs and materials, limit the range of their ut

Vitamin B12 is a cofactor for many enzymes, but it also functions as a catalyst in C-C bond-forming reactions. Herein, the impact of corrin structural modifications on their catalytic efficacy was examined. Derivatives with various substituents at c-

The pathogenesis of the cardiovascular system is often associated with dysfunction of soluble guanylate cyclase (sGC), which can be stimulated in both an NO-dependent and -independent manner. It was previously reported that PPIX and its amphiphilic d

A highly efficient procedure for the synthesis of bis-coumarins fused at the pyranone ring has been developed. The electron-rich phenols reacted with esters of coumarin-3-carboxylic acids, leading to substituted chromeno[3,4-c]chromene-6,7-diones. Th

We present a new method for the preparation of cobinamide (CN)2Cbi, a vitamin B12 precursor, that should allow its broader utility. Treatment of vitamin B12 with only NaCN and heating in a microwave reactor affords (CN)2Cbi as the sole product. The p

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
