Usage

Reactions

Biaryl bisphosphine ligand. The H8-BINAP ligand, as the ruthenium complex, catalyzes hydrogenation of unsaturated carboxylic acids to a higher ee than does BINAP. The ruthenium catalyzed hydrogenation of aryl propenoic acid to produce the drug Ibuprofen. Rhodium catalyzed asymmetric regioselective 1,4-addition of arylboronic acids to 3-substituted maleimides. Ligand for palladium-catalyzed enantioselective hydrogenation of substituted indoles. Rhodium-catalyzed enantioselective cyclization of γ-alkynylaldehydes with acyl phosphonates. Enantioselective synthesis of axially chiral 1-arylisoquinolines by Rh-catalyzed [2+2+2] cycloaddition. Enantioselective synthesis of 2,3-disubstituted indolines through Bronsted acid/Pd-complex-promoted tandem reactions.

NOVEL RUTHENIUM COMPLEX AND PROCESS FOR PRODUCING OPTICALLY ACTIVE ALCOHOL COMPOUND USING SAME AS CATALYST

The present invention provides: a novel ruthenium complex which has excellent catalytic activity with respect to reactivity in the reduction of a multiple bond, in particular, in the asymmetric reduction of a carbonyl compound, enantioselectivity, etc.; a catalyst which comprises the ruthenium complex; and a process for producing optically active compound, in particular, an optically active alcohol compound, using the catalyst. The ruthenium complex has a ruthenacyclic structure. The catalyst is a catalyst for asymmetric reduction which comprises the ruthenium complex.

Method for making an optically active diphosphine ligand

The present invention provides a method for making compound (1) by reacting compound (2) with phosphine oxide (3) in the presence of a transition metal/phosphine complex and optionally reducing the reaction product: STR1 where n represents 0 or 1; the double line having a continuous line and a dotted line represents a double bond or a single bond such that the ring having the double line forms a naphthalene ring or an octahydronaphthalene ring with an adjacent benzene ring; Tf represents a trifluoromethanesulfonyl group; and Ar represents a phenyl group, a substituted phenyl group or a naphthyl group. The present invention provides an economical way to produce compound (1) as a ligand of a complex useful as a catalyst for a variety of asymmetric synthesis reactions.
