  TiCl₄-Promoted Multicomponent Reaction:  A New Entry to Functionalized α-Amino Acids

  摘要：

  TiCl4-promoted multicomponent reactions involving N-tosyl imino ester, cyclic enol ether, and silane reagents in a single one-pot operation provide functionalized alpha-amino acids with multiple stereogenic centers in good to excellent yields. Cis/trans selectivities with optically active substituted dihydrofurans have been investigated.

  Asymmetric multicomponent reactions: convenient access to acyclic stereocenters and functionalized cyclopentenoids

  摘要：

  Asymmetric multicomponent reactions of optically active phenyl dihydrofuran, keto ester or N-tosyl imino ester, and allylsilane provided functionalized phenyl tetrahydrofurans with multiple stereogenic centers diastereoselectively. Cleavage of the resulting substituted tetrahydrofurans readily provided acyclic derivatives with three contiguous asymmetric centers via an acyloxycarbenium ion intermediate. Ring closing olefin metathesis, using Grubbs catalyst, afforded functionalized cyclopentene derivatives in optically active form. A one-pot tandem tetrahydrofuran ring cleavage followed by ring closing olefin metathesis also provided functionalized cyclopentenes in good yield. (C) 2008 Elsevier Ltd. All rights reserved.

  of the type [Pd(im)2Cl2] containing chiral imidazole ligands (im = 1-bornyloxymethylene imidazole, 1-fenchyloxymethylyne imidazole) were synthesized and structurally characterized. The square planar structure of one of the complexes was confirmed by the X-ray analysis. The new palladium complexes were tested as catalysts in various C C bond forming reactions, namely Suzuki–Miyaura, carbonylative Suzuki–Miyaura

  C1-symmetric chiral bisphosphine, FcPh-Binap (1), which possesses a single diferrocenylphosphino moiety together with a conventional Ph2P-substituent, was prepared in enantiomerically pure forms. Ligand 1 is sterically less demanding than Fc-Segphos (A), which has two diferrocenylphosphino groups, and showed higher activity than A in the rhodium-catalyzed asymmetric conjugate addition of phenylboronic

  Which gets activated? A versatile and highly enantioselective chiral Brønsted acid catalyzed method for the propargylation of aldehydes is described to provide a range of chiral homopropargylic alcohols. Computational studies support the belief that the chiral phosphoric acid activates the allenyl boronic acid pinacol ester reagent rather than the aldehyde.

  The synthesis of six members of the HetPHOX ligand class and the application of palladium complexes of these ligands to the intermolecular asymmetric Heck reaction is described. The tert-leucinol-derived ligands proved the most enantioselective, with palladium complexes of these ligands affording ee values of up to 96, 95 and 94 % in the phenylation, cyclohexenylation and naphthylation, respectively

  Two new heterocyclic diphenylphosphinooxazolines derived from thiophene and benzothiophene were prepared in moderate to good yield and these, and a range of related HETPHOX ligands, were applied in the intermolecular asymmetric Heck reaction. Phenylation of 2,3-dihydrofuran with the t-butyl-substituted thiophene-oxazoline ligand gave (R)-2-phenyl-2,3-dihydrofuran highly regioselectively with excellent
