Abstract: | Treatment of allyl furfuryl ethers and sulfides with butyllithium results in metallation at the free -position of the heterocycle, with partial Wittig rearrangement to the isomeric alcohols and sulfides and ring opening. With the benzo-derivatives, Wittig rearrangement and ring opening takes place.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 883–888, July, 1987. |
