Practical method for asymmetric addition of arylboronic acids to α,β-unsaturated carbonyl compounds utilizing an in situ prepared rhodium catalyst

A new practical method for the asymmetric Michael addition of arylboronic acids to α,β-unsaturated carbonyl compounds utilizing in situ generated chiral rhodium-binap-based catalyst has been developed to address the unavailability of the preformed catalys

A new and practical procedure for asymmetric 1,4-addition of boronic acids to α,β-unsaturated ketones catalyzed by Rh-(R)-Digm-BINAP system

Rh-catalyzed C-C bond asymmetric formation under basic conditions in organoaqueous or alcoholic solvents has been described using the atropoisomeric water-soluble ligand (R)-Digm-BINAP. The addition of phenylboronic acid to cyclohexenone has been efficien

A novel, C2-symmetric, chiral bis-cyclosulfinamide-olefin tridentate ligand in Rh-catalyzed asymmetric 1,4-additions

A C2-symmetric, chiral bis-cyclosulfinamide-olefin ligand composed of two 1-oxo-2,3-dihydro-1,2-benzisothiazole moieties with rigid skeletons and a conformationally flexible butenylene chain is disclosed for the first time. HRMS and 1/sup

Chiral N-aryl tert-butanesulfinamide-olefin ligands for rhodium-catalyzed asymmetric 1,4-addition of aryl boronic acids to cyclic enones

Chiral N-aryl sulfinamide-olefins which are readily synthesized via C-N coupling and nucleophilic substitution have been used as chiral ligands, which demonstrate moderate to excellent asymmetric catalytic performance in the rhodium-catalyzed asymmetric 1

Dicyclic sulfamide-alkene chiral ligand as well as preparation method and application

The invention discloses a dicyclic sulfamide-alkene chiral ligand as well as a preparation method and application. The structural characteristic of the dicyclic sulfamide-alkene chiral ligand is thatthe chiral ligand is a C2 symmetric compound formed by c

Room-temperature Rh-catalyzed asymmetric 1,4-addition of arylboronic acids to maleimides and enones in the presence of CF3-substituted MeOBIPHEP analogues

A Rh-based catalytic system implying electron-poor MeOBIPHEP analogues has been developed for the 1,4-addition of boronic acids to maleimides and enones under mild conditions at room temperature and led to succinimide derivatives and arylated cyclic ketones in good to excellent yields and ee. We uncovered the crucial role of the electronic and steric properties of diphosphine ligand and observed a strong boronic acid/ligand dependency in the case of maleimide derivatives and substrate/ligand matching in the case of cyclic enones.

Room-temperature rhodium-catalyzed asymmetric 1,4-addition of potassium trifluoro(organo)borates

For the first time the room-temperature rhodium-catalyzed asymmetric 1,4-addition of potassium aryltrifluoroborates to αβ-unsaturated substrates is described. Thanks to the use of a chiral diene as ligand for rhodium and triethylamine as base, to facilita

Highly practical catalytic asymmetric 1,4-addition of arylboronic acids in water using new hydrophilic chiral bicyclo[3.3.0] diene ligands

(Chemical Equation Presented) The first Rh-diene-catalyzed aqueous asymmetric 1,4-addition of α,β-unsaturated carbonyl compounds with arylboronic acids has been realized. By using a hydrophilic bicyclo[3.3.0] diene ligand, the reactions can be performed successfully in neat water at room temperature to afford the corresponding products in good yields and with very high enantioselectivities for both cyclic and linear substrates.
