摘要:A multidentate phosphite ligand is used in the catalytic synthesis of adiponitrile. The ligand is represented by the following general formula (I). The method of catalytic synthesis of adiponitrile comprises primary hydrocyanation, isomerization, and secondary hydrocyanation reactions, wherein the catalyst adopted each comprises a phosphite ligand-nickel complex composed of a nickel precursor and a multidentate phosphite ligand. The ligand molecule has a higher electron cloud density, and the phosphorus content capable of participating in coordination in the ligand molecule per unit mass is higher, so that the catalytic activity of the catalyst is improved, and the amount of the catalyst is reduced.

摘要:The present invention relates to a method for covalently attaching nucleosides and/or nucleotides on surfaces having reactive functional groups, where in a first step, the reactive functional groups are made to react with suitable derivatized nucleosides and/or nucleotides, and in a second step, they are converted with a protecting group reagent, so that a reaction product of the consecutive reaction interacts with electromagnetic radiation such that it can be quantitatively determined. The invention also relates to a method for determining the repetitive coupling yields in the synthesis of nucleotides where the free 3′ or 5′ hydroxy group of a selected nucleoside and/or nucleotide is converted with a compound of formula (I) n n nwhere L is a common suitable leaving group, the motif O—PX represents a phosphor amidite, a H-phosphonate a phosphonic acid ester, a phosphotriester, Yâ•?O or S, N is a nucleoside or a nucleotide derivative which subsequently reacts further with a protecting group reagent and the elimination of the leaving group (L), which is subsequently further eliminated. The quantity of the leaving group (L) eliminated in step b) is quantitatively determined in the form of its anion (L − ) by means of otical spectroscopy.

摘要:Non-natural amino acids such as 2-alkylated amino acids allow for the synthesis of a wider variety of peptidal and non-peptidal pharmaceutically active agents. A method of preparing a 2-alkyl amino acid involves a Michael-type addition of a nucleophile to a dialkyl 2-methylidenylpropan-1,3-dioate and the conversion of a ester moiety into an amino moiety. The present invention also discloses a method of preparing a class of iron chelating agents related to desferrithiocin, all of which contain a thiazoline ring. In this method, an aryl nitrile or imidate is condensed with cysteine, a 2-alkyl cysteine, or a cysteine ester.
