Abstract

Chan and coworkers developed [¹6] a convenient synthesis of salicylates by cyclocondensation of 1,3-bis(silyl enol ethers) [¹7] with 3-silyloxy-2-en-1-ones. In recent years, we have extended the scope of this chemistry and studied its application to the synthesis of a variety of functionalized arenes. [¹8] For example, we have reported formal [3+3] cyclocondensations of 1,3-bis(silyl enol ethers) with 1,1,3,3-tetraalkoxypropanes. [¹9] 3-Alkoxy-1-aryl-2-en-1-ones and 3-alkoxy-1- ...
