Reaction of enol ethers with alkynes catalyzed by transition metals: 5-exo-dig versus 6-endo-dig cyclizations via cyclopropyl platinum or gold carbene complexes
Nevado, Cristina,Cardenas, Diego J.,Echavarren, Antonio M.
, p. 2627 - 2635 (2003)
The intramolecular reaction of enol ethers with alkynes in methanol is catalyzed by electrophilic PtII, PdII, and AuIII chlorides and by a Cu1 complex to give five- or six-membered rings bearing dimethyl acetals
Solvent Effects on Manganese(III)-Based Oxidative Free-Radical Cyclizations: Ethanol and Acetic Acid
Snider, Barry B.,Merritt, John E.,Dombroski, Mark A.,Buckman, Brad O.
, p. 5544 - 5553 (2007/10/02)
Ethanol complements the typical solvent, acetic acid, for Mn(III)-based oxidative free-radical cyclizations.Cyclization of enol ether 1c to give gibberellic acid intermediate 6c is successfull in ethanol, but not in acetic acid.Ethanol acts as a reducing
