Design of new axially chiral NADH mimics. Mechanistic investigation of the enantioselective hydride transfer
Vasse, Jean-Luc,Dupas, Georges,Duflos, Jack,Quéguiner, Guy,Bourguignon, Jean,Levacher, Vincent
, p. 4613 - 4616 (2001)
This paper reports the design of a new axially chiral NADH model which relies on the configurational control around the C3-C=O chiral axis by means of a chiral relay installed on the cyclic structure. The conformational and configurational control of the
Continuous Flow Chiral Amine Racemization Applied to Continuously Recirculating Dynamic Diastereomeric Crystallizations
Kwan, Maria H. T.,Breen, Jessica,Bowden, Martin,Conway, Louis,Crossley, Ben,Jones, Martin F.,Munday, Rachel,Pokar, Nisha P. B.,Screen, Thomas,Blacker, A. John

A new, dynamic diastereomeric crystallization method has been developed, in which the mother liquors are continuously separated, racemized over a fixed-bed catalyst, and recirculated to the crystallizer in a resolution-racemization-recycle (R3) process. S
Diastereoselective desymmetrization of diarylphosphinous acid-borane amides under Birch reduction
Stankevi?, Marek
, p. 6082 - 6102 (2015/06/08)
Treatment of diarylphosphinous acid-borane amides possessing chiral amido functionality with an alkali metal solution in liquid ammonia induced a preferential dearomatization of one aryl substituent at phosphorus leading to the formation of non-equimolar amounts of diastereomers. Diastereoselectivity of dearomatization depends strongly on the structure of a chiral auxiliary.
Efficient, selective, and green: Catalyst tuning for highly enatioselective reactions of ethylene
Smith, Craig R.,Rajanbabu
supporting information; experimental part, p. 1657 - 1659 (2009/04/10)
Fine tuning of the biaryl and amino moieties of Feringa's phosphoramidite ligands yields structurally simpler, yet more efficient and selective, ligands for asymmetric hydrovinylation of vinylarenes and acylic 1,3-dienes. The enantioselectivities and yields observed in the formation of the 3-arylbutenes are among the highest for all asymmetric catalytic processes reported to date for the synthesis of intermediates for the widely used antiinflammatory 2-arylpropionic acids including naproxen, ibuprofen, fenoprofen, and flurbiprofen.
