Metabolism of dibenzothiophene by a Beijerinckia species [PDF]
Applied and Environmental Microbiology, 1977 Beijerinckia B8/36 when grown with succinate in the presence of dibenzothiophene, accumulated (+)-cis-1,2-dihydroxy-1,2-dihydrodibenzothiophene and dibenzothiophene-5-oxide in the culture medium. Each metabolite was isolated in crystalline form and characterized by a variety of chemical techniques, cis-Naphthalene dihydrodiol dehydrogenase, isolated ...

Cobalt‐Catalyzed Radical Ligand Transfer (RLT) Enables Remote‐Markovnikov Hydroamination of Alkenes
Angewandte Chemie, EarlyView.A cobalt‐catalyzed remote‐Markovnikov 1,3‐hydroamination of allyl carboxylates proceeds through MHAT, 1,2‐radical acyloxy migration (1,2‐RAM), and radical ligand transfer (RLT) from a Co‐N intermediate, providing protected amino alcohols. ABSTRACT Amino alcohols are prevalent in pharmaceuticals, agrochemicals, and functional materials, yet ...

Angewandte Chemie, EarlyView.A nickel‐catalyzed C–C cross‐coupling protocol employing bench‐stable glycosyl sulfonyl hydrazides as practical glycosyl radical precursors is reported. A variety of (hetero)aryl iodides underwent cross‐coupling under redox‐neutral conditions to afford structurally diverse unprotected C‐(hetero)aryl glycosides.
