Highly Stereoselective Carbon–Carbon Bond-forming Reactions on Cyclopropane Rings Using 1-(Methoxycarbonyl)cyclopropylzinc Bromides
Highly stereoselective Reformatsky reaction and Pd-catalyzed arylation using 1-(alkoxycarbonyl)cyclopropylzinc bromide proceeded to give the trans-adduct as the major product in good to high yields with good to excellent stereoselectivities.
