标题 :Synthesis of esters
发明人：COWAN KIPLIN D
权利人:PHILLIPS PETROLEUM CO
摘要:An organic ester is produced by conversion of an organic halide employing excess alkali metal carboxylate. A resultant reaction mass including solids comprised of alkali metal halide is obtained containing occluded in the solids portion an amount of otherwise difficult-to-recover desired ester product. At least a portion of said solids is recycled to the conversion whereby to prevent further occlusion of desired product. In an embodiment of the invention, potassium acetate salt is recycled for reuse.

摘要:Disclosed is a method for making an α-, ω-dihydroxy-terminated alkane, preferably butane-1,4-diol, by cathodically coupling a polymethylene halohydrin, preferably ethylene bromo-, or iodohydrin, in an aqueous elctrolytic bath maintained at a pH of between about 8 and 10.

标题 :Azetidinone alcohol disulfides and process for cyclization
发明人：KUKOLJA STJEPAN; PFEIL JANICE L
权利人:LILLY CO ELI
摘要:Azetidinone alcohol disulfides are synthesized by reduction of the corresponding aldehydes. The azetidinone alcohol disulfides are the substrates for a process which cyclizes these compounds to 1-oxa β-lactam compounds, employing a cyclizing reagent chosen from the class consisting of divalent mercury salts or trivalent phosphine compounds. The 1-oxa β-lactam compounds produced by this process are intermediates in the synthesis of 1-oxa β-lactam antibiotics.

标题:Process for penicillin epimerization
发明人：BLASZCZAK LARRY C
权利人:LILLY CO ELI
摘要:6β-acylaminopenicillin-1β-sulfoxides are epimerized to 6α-acylaminopenicillin-1β-sulfoxides using triethylamine and chlorotrimethylsilane. The 6α-acylaminopenicillin-1β-sulfoxides produced in this process are useful intermediates in the synthesis of 7β-acylamino-7α-alkoxy-3-methyl 1-oxa β-lactam acids, a class of 1-oxa β-lactam antibiotics.

权利人:LILLY CO ELI
摘要:4R,4'R bis[1-(2-N-3-methyl-4-al-Z-but-2-ene-oate)-2-oxo-3S-acylamino azetidine]disulfide compounds are prepared by reacting the corresponding 7α-acylamino-2α-alkoxy-3-methyl-3-cephem-4-carboxylates first with an N-chloro halogenating agent, e.g., N-chlorosuccinimide, then with an aqueous suspension of mercury dichloride and cadmium carbonate. The disulfide compounds produced in this invention are intermediates in the synthesis of the biologically active 7β-acylamino-7α-alkoxy-3-methyl 1-oxa β-lactam antibiotic compounds.

摘要:Aryl 4R[1-(2-N-3-methyl-4-al-Z-but-2-ene-oate)-2-oxo-3S-acylamino azetidinone]disulfides are prepared by reacting the corresponding 7α-acylamino-2α-alkoxy-3-methyl-3-cephem-4-carboxylates first with either phenylsulfenyl chloride or a monosubstituted-phenylsulfenyl chloride where the substituent is either chloro, methoxy, methyl or acetoxy. The disulfide compounds produced in this invention are intermediates in the synthesis of the 7β-acylamino-7α-alkoxy-3-methyl 1-oxa β-lactam acids, a class of antibiotic compounds.
