In Vitro Biosynthesis of the [Fe]-Hydrogenase Cofactor Verifies the Proposed Biosynthetic Precursors

Xile Hu, Huijie Pan

In the FeGP cofactor of [Fe]-hydrogenase, low-spin Fe-II is in complex with two CO ligands and a pyridinol derivative; the latter ligates the iron with a 6-acylmethyl substituent and the pyridinol nitrogen. A guanylylpyridinol derivative, 6-carboxymethyl-3 ...

Asymmetric (CpRh)-Rh-x(III)-Catalyzed Acrylic Acid C-H Functionalization with Allenes Provides Chiral gamma-Lactones

Nicolai Cramer, Shouguo Wang

A chiral cyclopentadienyl (Cp-x) ligand featuring the semi-saturated H8-binaphthyl backbone as the chiral element was developed. Its application potential was demonstrated by (CpRhIII)-Rh-x-catalyzed C-H bond functionalization of acryl acids and allenes, e ...

Reconstitution of [Fe]-hydrogenase using model complexes

Xile Hu, Matthew Wodrich, Tao Xu, Dafa Chen

[Fe]-Hydrogenase catalyses the reversible hydrogenation of a methenyltetrahydromethanopterin substrate, which is an intermediate step during the methanogenesis from CO2 and H-2. The active site contains an iron-guanylylpyridinol cofactor, in which Fe2+ is ...
