An efficient entry to planar chiral organometallic complexes via Pd-catalyzed asymmetric hydrogenolysis.

چکیده
Planar chiral chromium- and ruthenium-based arene complexes were prepared with high levels of enantioselectivity via a Pd-catalyzed asymmetric hydrogenolysis reaction using a bulky chiral phosphoramidite ligand. Key elements for the efficiency of the process are the use of DABCO as borane-trapping reagent as well as substantial kinetic resolution, which was found to enhance the stereochemical outcome of the reaction.

Synthesis of highly enantiomerically enriched planar chiral ruthenium complexes via Pd-catalysed asymmetric hydrogenolysis.
Key elements in this communication are a very efficient microwave synthesis of [RuCp(naphthalene)][PF(6)], the precursor of [RuCp(CH(3)CN)(3)][PF(6)], and a Pd-catalysed asymmetric hydrogenolysis to afford planar chiral ruthenium complexes with high levels of enantioselectivity using a bulky chiral phosphoramidite ligand.
متن کاملPalladium-catalyzed asymmetric hydrogenolysis of N-sulfonyl aminoalcohols via achiral enesulfonamide intermediates.
Hydrogenolysis is an important synthetic method in organic chemistry, and has been widely applied in industrial processes, natural product synthesis, and the removal of waste materials. In practice, most hydrogenolysis reactions have been used for the synthesis of racemic or achiral compounds. Very few studies on asymmetric homogeneous hydrogenolysis have been reported. The first example, repor...
متن کاملPd-catalyzed asymmetric allylic amination using easily accessible metallocenyl P,N-ligands.
Compared to their C1-symmetric counterparts, planar chiral C2-symmetric metallocenyl P,N-ligands are efficient chiral ligands for Pd-catalyzed asymmetric allylic aminations, providing a number of amination products with high enantioselectivities. A non-C2-symmetric ferrocenyl P,N-ligand (a by-product obtained during the synthesis of the above C2-symmetric species) was also found to be an effici...
متن کاملCatalytic enantioselective hydrogenolysis of [Cr(CO)3(5,8-dibromonaphthalene)].
Highly enantiomerically enriched (h-arene)tricarbonylchromium(0) complexes whose chirality originates from the 1,2disubstitution pattern of the arene and the coordination of the metal to one enantiotopic face of the arene are powerful chirons in asymmetric synthesis. Robust, planar chiral arene complexes also increasingly find application as chiral ligands in asymmetric catalysis. Enantiomerica...
متن کاملConfigurationally stable, enantioenriched organometallic nucleophiles in stereospecific Pd-catalyzed cross-coupling reactions: an alternative approach to asymmetric synthesis
Several research groups have recently developed methods to employ configurationally stable, enantioenriched organometallic nucleophiles in stereospecific Pd-catalyzed cross-coupling reactions. By establishing the absolute configuration of a chiral alkyltin or alkylboron nucleophile prior to its use in cross-coupling reactions, new stereogenic centers may be rapidly and reliably generated with p...
