One-pot synthesis of functionalized carbacycles by formal [3+3] cyclizations of 1,3-bis(silyl enol ethers) with 1,3-dielectrophiles

摘要

Lewis acid mediated [3+3] cyclizations of 1,3-bis(silyl enol ethers) with 1,3-dielectrophiles, such as 1,1,3,3-tetramethoxypropane, 3-silyloxy-2-en-1-ones and 1,1-diacylcyclopropanes, provide an efficient approach to a variety of functionalized arenes (such as salicylates and phenols) and other six-membered carbacyclic products.
