Design and synthesis of chiral ketones for catalytic asymmetric epoxidation of unfunctionalized olefins

A series of C2 symmetric chiral ketones were designed and synthesized for catalytic asymmetric epoxidation of unfunctionalized olefins. Among those ketones screened, (R)-7, (R)-9, and (R)-10 were found to be highly efficient catalysts for epoxidation of trans-stilbenes with enantioselectivities in the range of 84-95%. Convincing evidence was provided for a spiro transition state of dioxirane epoxidation. Through the 18O-labeling experiment, chiral dioxiranes were found to be the intermediates in chiral ketone catalyzed epoxidation reactions.

Separation of Enantiomeric Amino Acid Derivatives on Axially Chiral 1,1'-Binaphthyl-2,2'-bis(N-decylcarboxamide) as a Stationary Phase for Capillary Gas Chromatography

Axially chiral 1,1'-binaphthyl-2,2'-bis(N-decylcarboxamide) was utilized as a chiral stationary phase for capillary gas chromatographic separation of enantiomers.This stationary phase showed efficient differentiation for amino acid derivatives allowing complete separation of eleven N-trifluoroacetyl amino acid isopropyl esters.

Cyclic polyamides consisting of 1,1'-binaphthyls. 'Chiral twist' of glycine residues

Two cyclic polyamides were prepared from glycine and 1,1'-binaphthyls, and their structures have been determined by single-crystal X-ray analysis. Local conformations of glycines are twisted when they are sandwiched between two (R)-1,1'-bioaphthyls. Glycines are stretched into planer conformations when they are placed between an (R)1,1'-binaphthyl and an (S)-1,1'- binaphthyl. Conformations of these two cyclic polyamides in organic solvents and their interaction with other organic molecules are also discussed.

Homochiral 2,2'-bis(oxazolyl)-1,1'-binaphthyls as ligands for copper(I)- catalyzed asymmetric cyclopropanation

Homochiral 2,2'-bis[4-(alkyl)oxazol-2-yl]-1,1'-binaphthyls, which possess both binaphthyl axial chirality and carbon centred chirality, were prepared from 1,1'-binaphthyl-2,2'-dicarboxylic acid and 2-alkyl-2-aminoethanols in high yields. Asymmetric cyclopropanation of styrene with diazoacetates in the presence of 2 mol % of copper(I) triflate and (S)-2,2'-bis[(S)-4-(t- butyl)oxazol-2-yl]-1,1'-binaphthyl gave optically active 2- (phenyl)cyclopropane-carboxylates of up to 97% ee.

C2-symmetric zirconium Bis(Amidate) complexes with enhanced reactivity in aminoalkene hydroamination

Binaphthalenedicarboxamide zirconium complexes exhibit significantly enhanced catalytic activity in aminoalkene hydroamination reactions with respect to substrate scope (substrates without gem-dialkyl activation; cyclization of aminoheptenes), catalyst loading (as low as 0.5 mol %) and reaction temperatures (as low as 70 °C) compared to previous group 4 metal-based hydroamination catalyst systems.
