Effective activation of allylic ethers by boron oxide in palladium catalyzed allylic alkylation
Lu, Xiyan,Jiang, Xiaohui
, p. 139 - 142 (1989)
In the presence of boron oxide, allylic ethers react smoothly with carbonucleophiles to afford the allylation products by catalysis with Pd(PPh3)4 under neutral conditions.

Palladium-catalyzed allylic alkylation of α-sulfinyl carbanions can take place under biphasic conditions. These new conditions provide a simple, mild and efficient route to allylated sulfoxides in good yields. The reaction tolerates a wide variety of EWG
Intramolecular Ring Opening of Epoxides by Bis-Activated Carbanions. The Influence of Ring Size on Reactivity and Selectivity
Benedetti, Fabio,Berti, Federico,Fabrissin, Silvio,Gianferrara, Teresa
, p. 1518 - 1524 (2007/10/02)
A quantitative study on the effect of ring size in the intramolecular ring opening of epoxides by carbanions is described.Two series of substrates were examined: α,α-bis-sulfonyl ω-epoxides 1 and α-cyano-α-sulfonyl ω-epoxides 2; in each series the carbani
Cyclization of γ,δ-Epoxy-α-cyanosulphones. A Simple, Diastereoselective Route to Cyclopropane Carboxylic Acids.
Benedetti, Fabio,Berti, Federico,Risaliti, Amerigo
, p. 6443 - 6446 (2007/10/02)
cyclisation of α-cyano-α-sulphonyl-γ,δ-epoxy carbanions proceeds with high yields and complete diastereoselectivity, to yield cyclopropanolactones, useful intermediates in the synthesis of cis-substituted cyclopropane carboxylic acids.
