Asymmetric synthesis of propargylamides via 3,3′-disubstituted binaphthol-modified alkynylboronates
Wu, T. Robert,Chong, J. Michael
, p. 15 - 18 (2007/10/03)
(Chemical Equation Presented) Alkynylboronates derived from 3,3′-disubstituted-2,2′-binaphthols react with various N-acylimines to give the expected chiral propargylamides with up to 99% ee. This new methodology was applied to the first enantioselective s
Enantioselective aza-Henry reactions assisted by ZnII and N-methylephedrine
Palomo, Claudio,Oiarbide, Mikel,Halder, Rajkumar,Laso, Antonio,Lopez, Rosa
, p. 117 - 120 (2007/10/03)
(Chemical Equation Presented) Hooray aza-Henry! A combination of zinc triflate, an amine base, and (-)-N-methylephedrine (NME), which can be easily recovered and reused, leads to high enantioselectivities in the aza-Henry reaction of N-Boc-protected aldimines and nitromethane (see scheme; Boc = tert-butyloxycarbonyl).
Scope and limitations in sulfur ylide mediated catalytic asymmetric aziridination of imines: Use of phenyldiazomethane, diazoesters and diazoacetamides
Aggarwal,Ferrara,O'Brien,Thompson,Jones,Fieldhouse
, p. 1635 - 1643 (2007/10/03)
Imine aziridination using diazo-compounds and catalytic quantities of metal salts and sulfides has been investigated. A range of imines derived from benzaldehyde bearing electron-withdrawing groups (N-Ts,N-SO2CH2CH2SiMesu
