A new class of readily available and conformationally rigid phosphino-oxazoline ligands for asymmetric catalysis
A new class of conformationally rigid phosphino-oxazoline ligands 3 were synthesized via an efficient ortho-substitution of phenyl glycinol as the key step. Divergent synthetic routes for easy ligand modulation, as well as a procedure suitable for scale-up synthesis, were established. The catalytic potential of ligands 3 has been demonstrated in the highly enantioselective Ir-catalyzed hydrogen...
متن کاملTunable ligands for asymmetric catalysis: readily available carbohydrate-derived diarylphosphinites induce high selectivity in the hydrovinylation of styrene derivatives.
Only a limited number of ligands have been successfully employed for the Ni-catalyzed asymmetric hydrovinylation reaction. Diarylphosphonites prepared from readily available carbohydrates in conjunction with a highly dissociated counterion ([3,5-(CF3)2-C6H3)4B]- or SbF6-) effect the hydrovinylation of 4-bromostyrene or 4-isobutylstyrene under ambient pressure of ethylene with the best overall s...
متن کاملIon-paired chiral ligands for asymmetric palladium catalysis.
Conventional chiral ligands rely on the use of a covalently constructed, single chiral molecule embedded with coordinative functional groups. Here, we report a new strategy for the design of a chiral ligand for asymmetric transition-metal catalysis; our approach is based on the development of an achiral cationic ammonium-phosphine hybrid ligand paired with a chiral binaphtholate anion. This ion...
متن کاملNovel Bis-1,3,2-diazaphospholidine Ligands for Asymmetric Catalysis
A family of modularly designed chiral bis-1,3,2-diazaphospholidines with N-aryl substituents (NP-PN) is reported. These compounds have been prepared in two steps from readily available (R,R)-1,2-diaminocyclohexane and tetrachlorodiphosphines. Examples in the set differ in the backbone and the aryl substituents aiming at their application in asymmetric catalysis. Thus, [Rh(NBD)(NP-PN)]BF4 comple...
متن کاملNew Applications of Tridentate Bis(oxazoline) Ligands in Asymmetric Catalysis
Finding interactions between microRNAs and their mRNA targets is a challenging experimental and computational problem. While several novel experimental high throughput approaches have been developed for measuring miRNA expression, the amount of data generated from these technologies is dwarfed by the amount of data existing in current gene expression microarray repositories. Many microRNAs over...
