Two-Step Synthesis of Furans by Mn(III)-Promoted Annulation of Enol Ethers
Corey, E. J.,Ghosh, Arun K.
, p. 223 - 226 (1987)
Enol ethers, β-dicarbonyl compounds and the Mn(III) reagent Mn3O(OAc)7 react under mild conditions to form 1-alkoxy-1,2-dihydrofurans in good (70-98 percent) yields.The latter are readily converted to furans by acid catalyzed elimination of ROH.

Paragraph 0071; 0132; 0133; 0158; 0160; 0164-0167, (2016/10/10)
The present invention relates to a one-pot synthesis method of dihydrofuran derivatives using a ruthenium catalyst and, more particularly, to a one-pot synthesis method of dihydrofuran derivatives, which makes a reaction between cyclic/non-cyclic diazo dicarbonyl compound and olefin in the presence of ruthenium (II) phosphine complex as a reaction catalyst. The one-pot synthesis method of the present invention shortens time required for the reaction and improves synthesis yield. The diazo carbonyl compound represented by chemical formula 1, 2, or 3 reacts with olefin to form dihydrofuran derivatives through a [3+2] cyclization addition reaction.COPYRIGHT KIPO 2016
