New access to carbonyl ylides by the silicon-based 1, 3-elimination and their [3+ 2] cycloadditions to activated alkenes and alkynes: One-step synthesis of …
Abstract Simple aryl-substituted carbonyl ylides are generated by the silicon-based 1, 3- elimination of chloromethyl trimethylsilyl (α-aryl) methyl ethers promoted by flouride ion under mild and neutral conditions which provide an one-step synthesis of dihydrofurans and tetrahydrofurans via [3+ 2] cycloadditions to activated multiple π-bonds such as α, β- unsaturated alkenes and alkynes.
