An Interesting Rearrangement of Unsaturated Sulphonate and Thiosulphonate Esters
Serra, Armenio C.,Correa, Carlos M. M. da Silva
, p. 6653 - 6654 (1991)
Alkenyl tosylates and thiotosylates, in the presence of radical initiators, undergo radical rearrangements to the corresponding tetrahydrofuran and tetrahydrothiophen derivatives.
Copper-Catalyzed Oxysulfenylation of Enolates with Sodium Sulfinates: A Strategy to Construct Sulfenylated Cyclic Ethers
Gao, Yinglan,Gao, Yang,Tang, Xiaodong,Peng, Jianwen,Hu, Miao,Wu, Wanqing,Jiang, Huanfeng
, p. 1158 - 1161 (2016/03/15)
A new copper-catalyzed oxysulfenylation reaction of enolates with sodium sulfinates has been disclosed. A series of sulfenylated heterocycles including four- and seven-membered cyclic ether were obtained in mild to good yields. This reaction is proposed to go through a radical process, and the sulfur radical (RS?) may be a reactive species.
Preparation and synthetic applications of lithiated vinyl sulfones derived from 3-buten-1-ol and 4-penten-1-ol
Caturla, Francisco,Najera, Carmen
, p. 11449 - 11464 (2007/10/03)
Vinyl sulfones (E)-4-tosyl-3-bulen-1-ol (2) and its MOM-derivative 6, prepared by iodosulfonylation-dehydroiodination of 3-buten-1-ol(1), are regio and stereoselectively lithiated at die 4-position to afford intermediates 3 and 7, respectively. Tile prote
The Cyclosulfonation Reaction: A Comment on the Radical Reactions of 4-Pentenyl Tosylate
Craig, Donald C.,Durie, Alexander,Edwards, Gavin L.,Sinclair, David J.
, p. 1307 - 1310 (2007/10/02)
Attempted free radical rearrangement of the para-toluenesulfonyl ester of 4-penten-1-ol in carbon tetrachloride gives only the simple Kharash 1,2-adduct, instead of the 2-substituted tetrahydrofuran as claimed by Serra and da Silva Correa.
para-toluenesulfonyl iodide as a convenient, mild reagent for the preparation of functionalised cyclic ethers
Edwards, Gavin L.,Walker, Katherine A.
, p. 1779 - 1782 (2007/10/02)
Free radical addition of para-toluenesulfonyl iodide to alkenols occurs readily to give functionalised βiodosulfones as single regioisomers. Cyclisation to give cyclic ethers is effected by treatment with potassium carbonate in methanol. An anomalous reac
