are released. Since β-mercaptoketones are potent naturalaromacompounds occurring in many fruits, herbs and flowers, the discovery of an enzyme-independent molecular precursor for this class of high-impact molecules is of practical importance. Moreover, the formation of β-diketones and aldehydes by concomitant oxidation at the α-sulfur-position enhances the versatility of this class of aroma precursors
Synthesis of highly diastereo- and enantiomerically enriched tetracarbonyl(η3-allyl)iron(1+) complexes for allylic substitutions with silyl enol ethers and silyl ketene acetals
tetracarbonyl (η3-allyl)iron(1+) complexes 2a–d (2a–c: 20–53%, de > 90- ⩾ 95% or greater; 2d: 31–40%, ee ⩾ 99%) by means of an auxiliary controlled complexation (aux. = 8-phenylmenthyl) of diastereo- or of enantiopure (E)-configuration enoates 1 as starting materials is reported. The nucleophilic addition of various silyl enol ethers or silyl ketene acetals 3a–e to the complexes 2a–d followed by oxidative
