ChemInform Abstract: Samarium Diiodide Mediated Intramolecular Cyclization of Mixed Enone—Enoate Systems: A Simple Preparation of Spirocyclic Ethers.

Abstract

Ethers. -The cyclization of substrates with different ring size and length of the tether is achieved with 2 equiv. of SmI2 to prevent enone overoxidation. Spirocyclic ethers are obtained with different degrees of diastereoselectivity. -(MENG, J.; LIGHT, M. E.; KILBURN*, J. D.; DIXON, S.; Tetrahedron Lett. 52 (2011) 8, 928-931, http://dx.
