An efficient protocol for Sharpless-style racemic dihydroxylation
Eames, Jason,Mitchell, Helen J.,Nelson, Adam,O'Brien, Peter,Warren, Stuart,Wyatt, Paul
, p. 1095 - 1104 (2007/10/03)
Racemic dihydroxylation of alkenes is efficiently accomplished with catalytic osmium (added as OsCl3), stoichiometric K3Fe(CN)6 and quinuclidine under conditions similar to those of the Sharpless asymmetric hydroxylation.
Diastereoselective addition of metal-coordinated and 'naked' nucleophilic reagents to norephedrine derived 2-acyl-N-tosyl-oxazolidines
Poli, Giovanni,Maccagni, Elisa,Manzoni, Leonardo,Pilati, Tullio,Scolastico, Carlo
, p. 1759 - 1776 (2007/10/03)
The addition of tri-s-butyl borohydrides to the 2-acetyl-1,3-oxazolidine 1 could be directed with high selectivity to either the Si or the Re π-carbonyl face under chelating or non-coordinating conditions respectively. Addition of hydrides to the correspo
Asymmetric synthesis with diphenylphosphine oxides: Bicyclic aminals and oxazolidines as chiral auxiliaries
O'Brien, Peter,Warren, Stuart
, p. 3431 - 3444 (2007/10/03)
Syntheses of six novel phosphine oxide chiral auxiliaries are described. The auxiliaries are composed of the diphenylphosphinoyl (Ph2PO) group and either proline-derived bicyclic aminals or norephedrine-derived oxazolidines. One auxiliary is us
Diastereoselective Addition of Metal-coordinated and 'Naked' Tri-sec-butylborohydrides to a Norephedrine-derived 2-Acetyloxazolidine
Manzoni, Leonardo,Pilati, Tullio,Poli, Giovanni,Scolastico, Carlo
, p. 1027 - 1029 (2007/10/02)
The addition of tri-sec-butylborohydrides to the 2-acetyl-1,3-oxazolidine 1 can be directed with high selectivity to either the Si or the Re ?-carbonyl face under chelating or non-coordinating conditions, respectively.
