标 题:Synthesis of carbapenems using n-substituted azetidinones
发明人：DEXTRAZE PIERRE
权利人:BRISTOL MYERS CO
摘要:A novel process is disclosed for converting known 3,4-disubstituted azetidinones to carbapenems. The process proceeds through novel N-substituted intermediates and then cyclizes to the 4-position of the azetidinone to form the carbapenem.

摘要:A method of preparing tetrabromobenzoate compounds from tetrabromophthalic anhydride by reacting tetrabromophthalic anhydride with alcohol in the presence of a decarboxylation catalyst. The reaction may be carried out in an excess of alcohol, or with a near stoichiometric amount of alcohol by performing the reaction in an inert solvent.

标 题:Butenolide synthesis via carbonylation of vinylmercurials in the presence of inorganic salts
发明人：LAROCK RICHARD CRAIG
权利人:UNIV IOWA STATE RES FOUND INC
摘要:Compounds containing the butenolide ring have a wide variety of chemical uses. The invention is an improved method of synthesizing β-halobutenolides which are valuable intermediates in preparing a variety of butenolide ring containing compounds. The method comprises reacting an acetylenic alcohol with a mercuric halide to provide a vinylmercuric halide and carbonylating the vinylmercuric halide in the presence of a basic inorganic salt to provide a β-halobutenolide.
