Title:
METHOD FOR PRODUCING ENANTIOMER-ENRICHED LACTONES
Document Type and Number:
WIPO Patent Application WO2006058681
Kind Code:
A3
Abstract:
The invention relates to a method for producing enantiomer-enriched lactones by carbonylating lactones into anhydrides in the presence of a catalyst system, containing: A) at least one carbonylation catalyst A comprised of neutral or anionic transition metal complexes of metals Re, Co, Ru, Rh, Ir, Fe, Ni, Mn, Mo, W or mixtures thereof, and; B) at least one chiral Lewis acid B comprised of compounds of metals Mg, Ca, Sc, Y, a rare-earth element, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Al, Ga, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, In, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Tl and Pb, the compounds in the reaction conditions of the carbonylation existing in a coordinatively undersaturated manner.
