Strategy for the Construction of Functionalized Five-and Six-Membered Carbocycles. -Conjugate addition of the Grignard reagents (II) and (IV) to the nitro olefins (I) leads to the intermediate formation of nitronates, which are trapped as silyl nitronates and subsequently cyclized by intramolecular
