Synthesis of Functionalized Diaryl Ethers by [3+3] Cyclization of 1,3-Bis(Silyl Enol Ethers) with 2-Aryloxy-3-(silyloxy)alk-2-en-1-ones

Functionalized and sterically encumbered diaryl ethers were prepared by [3+3] cyclization of 1,3-bis(silyl enol ethers) with 2-aryloxy-3-(silyloxy)alk-2-en-1-ones.
