Two-electron oxidation of a diiron complex (1) containing a bulky S-to-S bridge with an exocyclic carbonyl group affords [1(OH)](+), which replicates the coordination structure and electronic configuration of H(air)(ox), and the chemically reversible reaction between 1 and [1(OH)](+) mimics the bioprocess of interconversion of the inactive H(air)(ox) and the active Hred states of the [FeFe]-hydrogenases.

A general synthesis for bridged bicyclic disulfide compounds has been refined and expanded from [3.2.1] to [2.2.1] and [4.2.1] systems. The chemical reactivity of these novel compounds has been probed through esterification and S-oxidation reactions.

The assignment of the long-standing problem of the stereochemistry of cis-2,5-dibromocyclopentanone has been performed by stereoselective reduction into cis, cis-2,5-dibromocyclopentanol, conversion of the latter alcohol into the 4-nitrobenzoate ester, and following H-1 NMR and X-ray crystallographic-analysis.

Asymmetric Intramolecular Desymmetrization of <i>meso</i>-α,α′-Diazido Alcohols with Aryldiazoacetates: Assembly of Chiral C<sub>3</sub> Fragments with Three Continuous Stereocenters

The chiral Cu-complex-catalyzed intramolecular interception of meso-α,α′-diazido alcohols with aryldiazoacetates is explored. Most of the enantioenriched α-imino esters with three continuous stereocenters are produced with good to excellent yield and enantioselectivity, and a chiral pocket model is proposed for rationalization of the asymmetric desymmetrization.
