Publikováno v: Tetrahedron Letters. 42:6401-6404

Demetallation of tricarbonyliron diene complexes is rapidly achieved by treatment with freshly prepared Raney nickel. The ligands which are totally hydrogenated during the decomplexation are easily isolated in high yields, without racemization, if ch

One-carbon Friedel-Crafts functionalizations of acyclic diene iron tricarbonyl complexes

Autor: Philippe Geoffroy, Michel Franck-Neumann, Paul Bissinger

Publikováno v: Tetrahedron Letters. 34:4643-4646

Iron tricarbonyl complexes of acyclic conjugated dienes undergo Friedel-Crafts reactions with alkoxychloromethanes to give selectively cis- or trans-alkoxy penta-2,4-diene complexes, depending on the work-up conditions. With thiochloroformates, the r

ChemInform Abstract: Aldol Condensation Reactions of Tricarbonyliron Complexes. Easy Access to Diastereomerically Pure 1,2,3-Trisubstituted 1,3-Diols from α-Substituted Dienone Complexes

Autor: Michel Franck-Neumann, Paul Bissinger, Philippe Geoffroy, Fabien Gumery

Publikováno v: ChemInform. 31

Tricarbonyliron complexes of α-substituted dienones are well suited starting compounds for the synthesis of diastereomerically pure 1,2,3-trisubstituted 1,3-diols of known configuration, among them 1,2,3-triols. This is achieved by aldol condensatio
