Inducing Enantioselectivity in a Dynamic Catalyst by Supramolecular Interlocking

The design of a new class of fluxional biphenyl bisphosphinite (BIBIPHOS) ligands decorated with amino acid-based diamide interaction sites is reported that undergo spontaneous desymmetrization. Hydrogenation of prochiral alkenes using Rh-BIBIPHOS results

Supramolecular Interlocked Biphenyl Ligands for Enantioselective Ti-Catalyzed Alkylation of Aromatic Aldehydes

The substitution of tropos 2,2′-biphenols with (S)-amino-acid-derived interaction sites in the 5,5′-position results in a spontaneous desymmetrization. This process is driven by well-defined intermolecular hydrogen bonding, which leads to diastereoselecti

Process for preparing biphenyl compounds

The present invention relates to a process for preparing a compound having the formula (I), said process comprising the following steps: a) the addition of an oxygen source into a solution of a compound of formula (II), in a water-miscible solvent, b) the addition of a laccase in the solution obtained after step a); and c) the possible recovering of the compound of formula (I) thus obtained.

NOVEL MANUFACTURING METHOD OF LOW MOLECULAR COMPOUND FROM LIGNIN

PROBLEM TO BE SOLVED: To provide a manufacturing method of dehydro divanillic acid dialkyl ester using lignin contained in a needle-leaves trees or the like as a raw material. SOLUTION: The manufacturing method of dehydro divanillic acid dialkyl ester through following process 1 to process 5 with using lignin as a raw material.

Supramolecular-directed chiral induction in biaryl derivatives

(Chemical Equation Presented) A thermodynamically controlled resolution has allowed for the generation of diastereomerically enriched complexes, by chirality transfer from an enantiopure building block to a dynamically racemic biaryl derivative. A switcha
