An efficient method for the construction of five- and six-membered cyclic vinyl ethers from unsaturated esters using stoichiometric titanium reagents to convert the esters to acyclic olefinic enol ethers which are then transformed to the desired products by catalytic ring-closing olefin metathesis with a molybdenum alkylidene complex is described.
Natural Benzofurans: Synthesis of the Arylbenzofuran Constituents of Sophora tomentosa
McKittrick, Brian A.,Scannell, Ralph T.,Stevenson, Robert
, p. 3017 - 3020 (2007/10/02)
The structure, 2-(2',4-dihydrophenyl)-5,6-methylenedioxybenzofuran (1), suggested for Sophora compound I has been confirmed by a synthesis in which the benzofuran heterocycle was constructed by an intramolecular Wittig reaction of an o-bromomethylphenyl a
