Full characterization of the adduct isolated in crystalline form from a solution of tetrakis(mu-trifluoroacetato) dimolybdenum(II) and (2S,3S)-butane-2,3-diol is reported herein. For this purpose X-ray crystallographic, spectroscopic, and computational methods were conducted. The single crystal X-ray diffraction analysis clearly indicates the cleavage of the MoMo quadruple bond in the chiral complex initially formed in situ after mixing the components. Cleavage product 2 shows two coordinated, symmetrically unequivalent (2S,3S)-butane-2,3-diol ligands associated with one Mo atom with different MoO bond lengths and MoOC bond angles. This inequivalence most likely reflects the engagement of the coordinated butanediol ligands in an intermolecular hydrogen bonding interaction with solvating butanediol molecules leading to the formation of an infinite helical chain pattern. Density functional theory (DFT) and time-dependent DFT calculations were used to provide support for the proposed structural assignment of 2 in acetonitrile and chloroform solutions, which were made on the basis of experimental CD and NMR results. Additional studies under anaerobic conditions have shown that the cleavage of the quadruple MoMo bond takes place only under aerobic conditions. Thus, it has been demonstrated that the changes in the shapes of the ECD curves observed over time are associated with spontaneous, air-oxidative cleavage of the quadruple MoMo bond and conversion of the Mo(II) to Mo(VI) centers.

Optically active poly(y-ketosulfide)s can be obtained by polyaddition of 1,3-dimercaptobenzene to prochiral di-unsaturated ketones in the presence of (-)-cinchonidine as promoter of asymmetric induction. As proved with low molecular-weight model compounds, the enantiomeric excess found in the addition product is related to steric hindrance and conformational rigidity of the ketonic reagent as well as to reaction temperature, in accordance with the high sensitivity of this type of homogeneous catalysis to substrate structure and experimental conditions.

The effect of cyclohexene ring conformation on the diastereoselectivity observed for Simmons-Smith cyclopropanation of 2-cyclohexen-1-one ethylene ketals was examined by using (5S)-5-tert-butyl-2-cyclohexen-1-one 1,2-ethanediol, (2R,3R)-2,3-butanediol, and (2S,3S)-2,3-butanediol ketals.Reagent chelation by the pseudoequatorial dioxolane oxygen atom was shown to result in more effective methylene transfer.This regiochemical preference can either antagonize or reinforce diastereoselectivity due to steric hindrance of the dioxolane oxygen atoms from dissymmetric placement of methyl appendages on the dioxolane ring.

2-Pyrones are frequently produced by microorganisms and often exhibit interesting bioactivities. Therefore, a short and easy synthetic access to these natural products is desirable. Synthetic routes to nectriapyrone, gibepyrone A, racemic gulypyrone A, (+)-germicidin C, (ent)-desoxygermicidin C and (ent)-prolipyrone A via a modular approach are presented, allowing the assignment of the absolute configurations of the latter three chiral compounds. The method failed for the synthesis of (ent)-phomapyrone B that was thus synthesized via a different route, resulting in an assignment of the absolute configuration of natural phomapyrone B.
