摘要:A process is provided for preparing azetidinones useful as intermediates in the synthesis of penems and as hypocholesterolemic agents, comprising reacting a β-(substituted-amino)amide, a β-(substituted-amino)acid ester, or a β-(substituted-amino)thiolcarbonic acid ester with a silylating agent and a cyclizing agent selected from the group consisting of alkali metal carboxylates, quaternary ammonium carboxylates, quaternary ammonium hydroxides, quaternary ammonium alkoxides, quaternary ammonium aryloxides and hydrates thereof, or the reaction product of: (i) at least one quaternary ammonium halide and at least one alkali metal carboxylate; or (ii) at least one quaternary ammonium chloride, quaternary ammonium bromide, or quaternary ammonium iodide and at least one alkali metal fluoride, wherein a quaternary ammonium moiety of the cyclizing agent is unsubstituted or substituted by one to four groups independently selected from the group consisting of alkyl, arylalkyl and arylalkyl-alkyl.

标 题 :Direct synthesis by living cationic polymerization of nitrogen-containing polymers
发明人：CHERADAME HERVE M; CHEN FRANK J; STANAT JON E R; NGUYEN HUNG A; TABAR BEHROOZ R
权利人:EXXON CHEMICAL PATENTS INC
摘要:A method is provided for the direct synthesis by living cationic polymerization of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cyano, carbonylamino, cyanato, thiocyanato or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or a tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.

标 题 :Method of identifying and assessing DNA euchromatin in biological cells for detecting disease, monitoring wellness, assessing bio-activity, and screening pharmacological agents
发明人：FERGUSON GARY WILLIAM
权利人:G6 SCIENCE CORP
摘要:The present invention is a method of identifying and assessing DNA euchromatin in biological cells. The amount and/or distribution of DNA euchromatin generally relates to RNA/protein synthesis, which may change in certain conditions, such as disease, and/or cellular response to environmental and/or chemical agents. The present invention detects the potential presence of disease by assessing DNA euchromatin in ostensibly normal cells and similarly provides means to monitor and assess treatment response. The present invention may also be used to assess how application (or removal) of influences, such as environment, radiation, chemical agents, medications, herbs, vitamins, etc., interact to effect cells, establishing uses in monitoring wellness and pharmacological screening. Additional uses include assessing age related disorders, allergies, infections, Alzheimer's disease, ‘Time of Death’, chronic fatigue syndrome, etc. The method may be advantageously applied to biological cells including micro-organisms, plants, animals, or cultured cells, alone or in conjunction with other markers.
