Diastereoselective synthesis of half-sandwich chiral-at-metal cobaltacycles by oxidative cyclisation.

چکیده
Reaction of chiral ester linked diynes with chlorotris(triphenylphosphine)cobalt(I) and sodium cyclopentadienide gave (η(5)-cyclopentadienyl)(triphenylphosphine) cobaltacyclopentadiene complexes as single chiral-at-metal diastereoisomers, including a non-racemic example synthesised in three steps from (S)-3-butyn-2-ol.

Reaction of [IrCp*Cl2 ]2 with ferrocenylimines (Fc=NAr, Ar=Ph, p-MeOC6 H4 ) results in ferrocene C-H activation and the diastereoselective synthesis of half-sandwich iridacycles of relative configuration Sp *,RIr *. Extension to (S)-2-ferrocenyl-4-(1-methylethyl)oxazoline gave highly diastereoselective control over the new elements of planar chirality and metal-based pseudo-tetrahedral chiralit...
متن کاملAn atmosphere and light tuned highly diastereoselective synthesis of cyclobuta/penta[b]indoles from aniline-tethered alkylidenecyclopropanes with alkynes.
Metal-free and environmentally friendly synthesis highly controlled by natural sources like visible light and air (or oxygen) is always a pursuit of green chemistry. In this paper, an atmosphere and light tuned highly diastereoselective synthesis of two important polyheterocyclic skeletons: cyclobuta/penta[b]indoles from aniline-tethered alkylidenecyclopropanes with alkynes, has been developed....
متن کاملHighly diastereoselective synthesis of 3-indolylglycines via an asymmetric oxidative heterocoupling reaction of a chiral nickel(II) complex and indoles.
The asymmetric synthesis of 3-indolylglycine derivatives was achieved by an oxidative heterocoupling reaction. This method for the selective C-3 functionalization of unprotected indoles with the chiral equivalent of a nucleophilic glycine nickel(II) complex afforded adducts with high diastereoselectivities. The decomposition of adducts readily afforded 3-indolylglycine derivatives in high yields.
متن کاملThe bright future of stereoselective synthesis of co-ordination compounds
Transfer of chirality during the build-up of molecules has been applied innumerable times in organic chemistry since the end of the 19th century, when it was introduced in the so-called asymmetric synthesis by E. Fischer. Although analogous reactions were introduced in co-ordination chemistry in its early development, diastereoselective reactions have not been applied in a very systematic way f...

Planar chiral h6-arene chromium(0) complexes are finding increasing application in the synthesis of enantioenriched compounds by serving as enantiopure starting materials or ligands for catalytic asymmetric processes.[1,2] Whereas early methods of generating enantiopure 1,2-disubstituted h6-arene chromium(0) complexes relied on resolution of racemates,[3] many methods have been developed recent...
