Abstract
An efficient and straightforward nucleophilic substitution reaction between 2-(trifluoromethyl)-2-hydroxy-2H-chromenes and various silyl enol ethers promoted by Lewis acid has been studied. A series of novel 4-functionalized-2-trifluoromethyl-3-ethoxycarbonyl-4H-chromenes were prepared in good yields under mild conditions.
