标题:Synthesis of dithioester chain transfer agents and use of bis(thioacyl) disulfides or dithioesters as chain transfer agents
发明人：RIZZARDO ENZIO; THANG SAN HOA; MOAD GRAEME
权利人:E I DUPONT NEMOURS AND COMPANY; COMMW SCIENT IND RES ORG
摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.

标 题:Diversity-oriented synthesis of N,N,O-trisubstituted hydroxylamines from alcohols and amines by N—O bond formation
发明人：CRICH DAVID; HETTIKANKANAMALAGE ASIRI; HILL JARVIS
权利人:UNIV GEORGIA
摘要:In one aspect, the disclosure relates to a method for the direct synthesis of complex N,N,O-trisubstituted hydroxylamines by N—O bond formation. In another aspect, the method can successfully be employed using a wide variety of commercially available alcohols and secondary amines and enables the construction of large fragment-based libraries of trisubstituted hydroxylamines for drug discovery purposes. Also disclosed are N,N,O-trisubstituted hydroxylamines having low basicity, high stability at ambient temperatures, and an inherent lack of reactivity towards acetylating and sulfonylating enzymes that confer mutagenicity on less-substituted hydroxylamines.

标题 :Synthesis of polymers containing integral antibodies
发明人：NOWINSKI ROBERT C; HOFFMAN ALLAN S
权利人:GENETIC SYSTEMS CORP
摘要:A method is disclosed for the de novo synthesis of antibody-containing polymers and the preparation of a class of polymerizable compounds used in the synthesis of such antibody-containing polymers. Antibody-containing polymers formed from monomer/antibody conjugates and nonderivatized polymerizable compounds can be varied in formation of the polymer to provide control of (a) molecular spacing, steric accessibility and the number of antibody molecules that are integrally incorporated into the polymer backbone, and (b) the chemical and physical structure of the polymer itself, thus enabling specific tailoring of antibody-containing polymers for particular end-use application. Also disclosed is a method for the selective removal of a compound from a solution or suspension thereof using monomer/receptor conjugates where the compound has the capacity to bind to the receptor in the conjugate. The bound compound is removed by polymerization - induced separation of the monomer/receptor--compound complex from solution.

摘要:The present invention relates to a novel biocatalytic process for the stereoselective preparation of alpha amino amide compounds catalyzed by NHase enzymes. A further aspect of the invention relates to novel NHase enzymes as well as further improved NHase enzyme mutants, nucleic acid molecules encoding these enzymes, recombinant microorganisms suitable for preparing such enzymes and mutants. Another aspect of the invention relates to a chemo-biocatalytic process for the preparation of lactam compounds comprising the new catalytic process for the preparation of alpha amino amide compounds catalyzed by NHase enzymes, as well as the chemical oxidation of the alpha amino amide by applying certain chemical oxidation catalysts suitable for converting the alpha amino amide under retention of its stereochemical configuration to the respective lactam. The novel chemo-biocatalytic process is particularly suited for the synthesis of valuable pharmaceutical compounds, like in particular (S)-Levetiracetam.
