权利人:CALIFORNIA INST OF TECHN
摘要:This invention relates generally to the synthesis of E-macrocycles using stereoretentive ruthenium olefin metathesis catalysts supported by dithioiate ligands. Macrocycles were generated with excellent selectivity (>99% E) and in moderate to high/good yields (47% to 80% yield; 58% to 80% yield) from diene starting materials bearing two E-olefins or bearing one E-olefin and one terminal olefin, A variety of rings were constructed, ranging from 12- to 18-membered macrocycles, including the antibiotic recifeiolide. The invention has utility in the fields of organometallics and organic synthesis.

标题 :Highly efficient synthesis of Z-macrocycles using stereoretentive, ruthenium-based metathesis catalysts

摘要:A highly efficient, Z-selective ring-closing metathesis system for the formation of macrocycles using a stereoretentive, ruthenium-based catalyst supported by a dithiolate ligand is reported. This catalyst is demonstrated to be remarkably active as observed in initiation experiments showing complete catalyst initiation at −20° C. within 10 min. Using easily accessible diene starting materials bearing a Z-olefin moiety, macrocyclization reactions generated products with significantly higher Z-selectivity in appreciably shorter reaction times, in higher yield, and with much lower catalyst loadings than in previously reported systems. Macrocyclic lactones ranging in size from twelve-membered to seventeen-membered rings are synthesized in moderate to high yields (68-79% yield) with excellent Z-selectivity (95%-99% Z).

摘要:There are described novel cross-linked polymers based on bis-silane, bis-thioether, bis-sulphoxide, bis-sulphone and butane-di-yl derivatives of polysaccharides and oligosaccharides, their shaping as support materials useful for the separation or preparation of enantiomers; a process for preparing the said cross-linked polymer compounds, a process for preparing balls of support materials containing the said cross-linked polymer compounds; a method of obtaining balls of support materials useful in chromatography or in organic synthesis; and the use of the said support materials containing the cross-linked polymer compounds in separation or in preparation of enantiomers, through employment in chromatography or organic synthesis processes in a heterogeneous medium; and the use of the said cross-linked polymer compounds in the form of membranes in processes using percolation through membranes for the separation or the preparation of enantiomers.

标题:Cross-linked chiral compounds and methods of making thereof
发明人：DUVAL RAPHAEL; LEVEQUE HUBERT
权利人:EKA CHEMICALS AB
摘要:The invention relates to a method which comprises synthesizing bifunctional compounds then chiral compounds from the bifunctional compounds, also to synthesizing supports comprising these chiral compounds, and the use of these supports for preparing or separating enantiomers, or for asymmetric synthesis. The invention also relates to bifunctional compounds, their use as a source of functionalized polymers, and to the chiral compounds, also to the use of these chiral compounds in a chiral support in the form of a three-dimensional network or for separating or preparing enantiomers, principally for analytical or preparative chromatography, and in a support for the production of chiral molecules by asymmetric synthesis.
