Lewis acid-promoted nitroolefination of enol silyl ethers has been developed. Enol ethers 1, 4, 5, and 6 derived from lactones and lactams furnished nitroolefines 2, 7, 8, and 9, respectively in 60-99% yields by the treatment with 3 in the presence of Lewis acids. Asymmetric nitroolefination of 5a and 6a with 12 gave 8a and 9a in 75% and 73% ee, respectively.
