Synthesis and enantiomeric selectivity of chiral crown ethers

Condensation of (4S,5S)-4,5-dihydroxymethyl-2-substituted dioxolanes with polyethylene glycols ditosylates yielded new chiral crown ethers. By potentiometry the enantioselectivity of complexing between the compounds obtained and L- and D-valine methyl ester hydrochlorides was evaluated.

A novel chiral manganese-tetraamide macrocycle complex covalently attached to magnetite as recyclable catalyst for aerobic asymmetric epoxidation of olefins

A novel Mn complex containing N4-tetradentate tetraamide macrocyclic ligand (L) derived from chiral diethyl-2,3-benzylidene-L-tartrate and polyamidoamine dendrimer on Fe3O4@SiO2 surface was synthesized. The nanocomposite particles were investigated by SEM, XRD, VSM, EPR and FTIR. The nanocomposite showed high catalytic activity and selectivity for the epoxidation of linear terminal, cyclic and most of the aromatic olefins by O2 in the presence of isobutyraldehyde under mild conditions; epoxide selectivity 87–100%, enantiomeric excess 53–100%. The catalyst could be separated and recovered from the reaction system by applying an external magnetic field and reused for four cycles without the loss of activity after each cycle. Total TON of 16957 was obtained after four cycles.

A highly efficient, enantioselective and recyclable mesoporous silica-based Mn(ii) catalyst for asymmetric oxidation of thioanisole

The development of environmentally benign reactions is an important goal in synthetic organic chemistry and chemical engineering. However, catalytic enantioselective oxidations using transition-metal complexes are limited when the oxidant is hydrogen peroxide. A hydrazone based asymmetric ligand (H2L) was used to prepare a heterogeneous catalyst by the immobilization of its manganese complex, [{Mn(H2O)2Cl2}2(H2Btar)] (1), on mesoporous support SBA-15 via the post grafting method (H2L = 2,3-O-4-hydroxybenzhydrazidebenzylidene-d-tartrate). The heterogeneous asymmetric catalyst 1-SBA15 was characterized by elemental analysis; small angle X-ray diffraction (SAX), scanning electron microscopy (SEM), nitrogen sorption measurement, Fourier transform infrared spectroscopy and EPR spectroscopy. The asymmetric oxidation of thioanisole (PhSMe) was achieved with hydrogen peroxide in the presence of 1-SBA15 in excellent conversion and enantioselectivity (>99% ee). Compared to a homogeneous catalyst, the heterogenized catalyst is more stable and can be recycled four times without any significant loss of activity. Immobilization of complex 1 onto SBA-15 increased the selectivity toward sulfone in the oxidation.
