Described the first asymmetric Kumada reaction of alkyl electrophiles, specifically the cross-coupling of racemic α-bromoketones with aryl Grignard reagents. Several features of this survey are of interest.<\/p>\n

First, the coupling takes place at very low temperatures (-40 or -60 °C), which enables asymmetric synthesis of easily racemic α-aryl ketones.<\/p>\n

Second, dialkyl ketones undergo enantioselective coupling with good ee and yield.<\/p>\n

Third, ready-made bis(oxazolines) were demonstrated for the first time to be efficient ligands for cross-coupling of alkyl electrophiles, opening the door to new opportunities in asymmetric catalysis.<\/p>\n
