In the reactions of functionalized organometallics and of cyclopropanation reagents with chiral nitroalkenes 3 the conjugateaddition proceeded with modest to high diastereoselectivity depending on the metal and the substituent R. X-ray analyses showed the nitrocyclopropanes 6, formed with high stereoselectivity, to be syn-derivatives.
