Silver tetrafluoroborate induced reaction of trimethylsilyl enol ethers with 2,3-diiodo-1-(phenylsulfonyl)-1-propene as a method for preparing substituted furans

Add time:07/17/2019    Source:sciencedirect.com

Treatment of 2,3-diiodo-1-(phenylsulfonyl)-1-propene (DIP) with various trimethylsilyl enol ethers in the presence of silver tetrafluoroborate gives alkylation products derived from SN2 displacement of the terminal halide. These compounds readily cyclize with base to produce substituted furans.
