摘要:The present invention relates to water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl and its use as organometallic catalysts for asymmetric synthesis of optically active compounds. Asymmetric reactions of the present invention include those reactions in which organometallic catalysts are commonly used. Such reactions include, but are not limited to, reduction and isomerization reactions on unsaturated substrates and carbon--carbon bond forming reactions. Examples of such reactions include, but are not limited to, hydrogenation, hydroboration, hydrosilylation, hydride reduction, hydroformylation, alkylation, allylic alkylation, arylation, alkenylation, epoxidation, hydrocyanation, disilylation, cyclization and isomerization reactions. n The catalysts of the present invention provide the advantage of functioning in the presence of water without loss in enantioselectivity relative to the nonsulfonated BINAP catalyst in an organic solvent. As a result, the catalysts of the present invention may be employed in water, water miscible solvents, in aqueous--organic two phase solvent systems and in supported aqueous phase catalysts in organic solvents without loss in enantioselectivity. Further, the catalysts of the present invention may also be effectively employed in highly polar solvents such as primary alcohols and ethylene glycol. n The present invention also relates to a method for conducting asymmetric reactions on prochiral unsaturated bonds contained within a compound using the water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl organometallic catalysts of the present invention.

摘要:A practical and high-yielding method for the efficient, one-step synthesis of diverse classes of N,N′-differentiated sulfamides employs a wide range of amino alcohols and simple amines using Burgess-type reagents. This methodology extends the application and availability of sulfamides within the fields of chemical biology, medicinal chemistry, asymmetric synthesis, and supramolecular chemistry.

摘要:The invention relates to methods for selectively converting a cysteine residue in a peptide or protein to the dehydroalanine (Dha) residue. The method also works on selenocysteine and substituted cysteine and selenocysteine residues, resulting in the Dha residue which may be converted to any natural or unnatural amino acid residue desired without the alteration of the remainder of the peptide or protein. The invention also allows ligation of a desired peptide at any point rather than at a point where there should be a naturally occurring cysteine, thereby allowing native chemical ligation to be used in the synthesis of peptides that do not contain cysteine. The methodology allows for the synthesis of very large peptides.

摘要:The selective addition of a compound having an activated carbon atom onto the carbon atom in the 4-position of a buta-1,3-diene carrying a hydrocarbon substituent on the carbon atom in the 2-position is achieved by reacting the compound having the activated carbon atom with the buta-1,3-diene carrying the hydrocarbon substituent in water or in an aqueous-alcoholic mixture in the presence of a catalyst which consists of at least one water-soluble phosphine and at least one rhodium compound, the catalyst being in solution in the water or aqueous alcoholic mixture. The products obtained are useful as precursors of intermediates for the synthesis of vitamins and perfumes.
