标题 :Intermediates for the synthesis of 19-nor vitamin D compounds
发明人：DELUCA HECTOR F; SCHNOES HEINRICH K; PERLMAN KATO L
权利人:WISCONSIN ALUMNI RES FOUND
摘要:New intermediate compounds that can be used effectively for the synthesis of a broad range of 1 alpha -hydroxy-19-nor-vitamin D compounds. These novel intermediates are characterized by a group selected from hydroxy methyl (-CH2OH), carboxaldehyde (-CHO), and carboxy ester (-COOAlkyl) at the carbon 22 position of the side chain of a 19-nor-vitamin D nucleus. Intermediates of this type are useful for the introduction of side chain units and thus represent important synthons for the preparation of many different 19-nor-vitamin D compounds.

摘要:New chiral phosphinopyrrolidine compounds of the general formula: ##STR1## wherein R 1 is hydrogen or --COA 1 , --COOA 2 , --CONHA 3 , --SO 2 A 4 or --PO(A 5 ) 2 , A 1 , A 2 , A 3 , A 4 and A 5 each represents independently alkyl or aryl, R 2 is phenyl, di(lower-alkyl)aminophenyl, lower-alkoxyphenyl or 3,5-dimethyl-4-methoxyphenyl, and R 3 is phenyl, lower-alkylphenyl, di(lower-alkyl)aminophenyl, lower-alkoxyphenyl or 3,5-dimethyl-4-methoxyphenyl, with the proviso that R 2 and R 3 may not simultaneously by phenyl, p-di(lower-alkyl)-aminophenyl or p-lower-alkoxyphenyl, as well as the use of these compounds as ligand for a metal complex catalyst for asymmetric synthesis of optically active compounds. The new chiral phosphinopyrrolidine compounds are useful ligands which attain both of high optical yield and high reaction efficiency in catalytic asymmetric reduction.

标题 :Synthesis of polyphosphazenes with sulfonimide side groups
发明人：ALLCOCK HARRY R; HOFMANN MICHAEL A; AMBLER CATHERINE M; MAHER ANDREW E; WOOD RICHARD M; WELNA DANIEL T
权利人:PENN STATE RES FOUND
摘要:The invention relates to sulfonimide bearing phenolic compounds and the use of those compounds to produce polyphosphazenes functionalized by one or more of those compounds alone, or in combination with cosubstituents. The invention also relates to blends of sulfonimide functionalized phosphazene polymers with other polymers, membranes formed of the functionalized polymers, and the use of those membranes in devices such as fuel cells.

标题:Synthesis of phosphorus based ligands
发明人：BERENS ULRICH
权利人:CIBA SC HOLDING AG
摘要:Chiral ligands of the formula I or II, may be obtained in high enantiomeric purity from compounds of the formulae III or IV, respectively, with suitable phosphines, where the symbols R₁, R, n, R₃, R₄, R' are as described in claim 1. The products may be converted into transition metal complexes which are useful as catalysts for asymmetric hydrogenation reactions.

摘要:The present disclosure is related to the development of improved fertilizer for precision and sustainable agriculture. A method was developed wherein efficient NPK nanocomposite for plant nutrition was synthesized in a single step using aerosol science and technology concepts. Further a formulation was prepared by addition of ZnO, TiO 2 and other nanoparticles to the NPK nanocomposite. Also, an aerosol based foliar application technique was developed for the precise delivery of nanoparticles to the plants.
