摘要:Disclosed is a process for the preparation of a 4-substituted azetidinone derivative, which comprises reacting an azetidinone derivative and an amide compound in the presence of a magnesium compound such as those represented by the following formulas (II): n and (IV): n represented by the following formula (III): n n n MgR 5 R 6   (III) n n n wherein R 5 represents a C 1-12 alkyl group, a C 2-5 alkenyl group, a 5- to 8-membered alicyclic group which may be substituted by a lower C 1-4 alkyl group, a phenyl group which may be substituted by a lower C 1-4 alkyl group, a lower C 1-4 alkoxy group or a halogen atom or a benzyl group which may be substituted by a lower C 1-4 alkyl group, a lower C 1-4 alkoxy group or a halogen atom, and R 6 represents a halogen atom, a methanesulfonyloxy group, a benzenesulfonyloxy group, a p-toluenesulfonyloxy group, a trifluoromethanesulfonyloxy group, an acetoxy group which may be substituted by a halogen atom or a cyano group or an OR 7 group (R 7 representing a lower C 1-4 alkyl group, a substituted or unsubstituted phenyl group or a substituted or unsubstituted benzyl group). The process provides an industrially excellent process for the preparation of a 4-substituted azetidinone derivative which permits the selective preparation of an intermediate for the synthesis of a carbapenem antibacterial agent having a desired 1-β′ configuration.

标 题 :Synthesis of 5-aroyl-1-hydrocarbylpyrrole-2-acetic acid
发明人：ZAIKO EDWARD J
权利人:ETHYL CORP
摘要:The reaction between a 5-cyano-1-hydrocarbylpyrrole-2-acetic acid and an aryl Grignard compound to produce a ketimine salt-containing reaction intermediate is improved by performing such reaction in an aromatic ether reaction medium at a temperature above about 100° C. As compared to the previously known process, the reaction rate is markedly increased without loss of selectivity. Also, the water insolubility of aromatic ethers simplifies product work-up and recovery, reduces product losses, and facilitates solvent recovery and recycle. Preferably, the aryl Grignard reagent is prepared at the outset in tetrahydrofuran or methyl tetrahydrofuran--solvents in which such Grignard reagents are readily and safely produced. The resultant Grignard solution may then be employed in forming the aromatic ether-containing reaction medium in which the above reaction is conducted.

标题 :Synthesis of boronic esters and boronic acids using grignard reagents
发明人：CLARY JACOB W; SINGARAM BAKTHAN
权利人:CLARY JACOB W; SINGARAM BAKTHAN; UNIV CALIFORNIA
摘要:Boronic esters and boronic acids are synthesized at ambient temperature in an ethereal solvent by the reaction of Grignard reagents with a boron-containing substrate. The boron-containing substrate may be a boronic ester such as pinacolborane, neopentylglycolborane, or a dialkylaminoborane compound such as diisopropylaminoborane. The Grignard reagents may be pre-formed or generated from an alkyl, alkenyl, aryl, arylalkyl, heteroaryl, vinyl, or allyl halide compound and Mg 0 . When the boron-containing substrate is a boronic ester, the reactions generally proceed at room temperature without added base in about 1 to 3 hours to form a boronic ester compound. When the boron-containing substrate is a dialkylaminoborane compound, the reactions generally proceed to completion at 0° C. in about 1 hour to form a boronic acid compound.
