  Electronic effects of aryl-substituted bis(oxazoline) ligands on the outcome of asymmetric copper-catalysed C–H insertion and aromatic addition reactions

  摘要：

  The effect of the modification of bis(oxazoline) ligands on the outcome of copper-catalysed C-H insertion and aromatic addition reactions is described. In general, these reactions display minimum sensitivity in terms of enantiocontrol to variation of the electronic properties of the aryl moiety of the ligand however, some influence is observed for C-H insertions employing naphthyl-substituted bis(oxazolines) and for aromatic addition reactions of biphenyl diazo ketone substrates. The synthesis of the modified bis(oxazolines), which include four novel structures, is also described. (C) 2013 Elsevier Ltd. All rights reserved.

  text] Two syntheses of a model system of the DEF ring system of complestatin and chloropeptin are described. The key step in both of these syntheses involves the formation of the biaryl linkage using a palladium-catalyzed Suzuki cross-coupling reaction and a catalytic enantioselective ene reaction to form the 6-bromo-D-tryptophan. Additionally, ring contraction of the 17-membered DEF ring system of complestatin

• From Styrenes to Enantiopure α-Arylglycines in Two Steps
  作者：K. Laxma Reddy、K. Barry Sharpless

  DOI：10.1021/ja9728177

  日期：1998.2.1

  Direct enantioselective synthesis of (R)- and (S)-N-Cbz- or N-BOC-protected alpha-arylglycinols from styrenes via catalytic asymmetric aminohydroxylation, with enantioselectivities up to 99% and isolated yields up to 80%, is described. In a subsequent oxidation step, these glycinols yield the corresponding carbamate-protected alpha-arylglycines.
