, p. 624 - 626 (2008/03/12)
2-Methyl-, 2-(methoxycarbonyl)methyl-, and 2,2-[(ethoxycarbonyl) (methoxycarbonyl)]methyl-5-phenylpyrroles are prepared from the corresponding 3-butynyl and 4-(methoxycarbonyl)-3-butynyl phenyl ketone O-pentafluorobenzoyl oximes by amino Heck cyclization
Synthesis of Dihydropyrrole and Pyrrole Derivatives by Radical Cyclization of γ,δUnsaturated Ketone O-Acetyloximes

, p. 2003 - 2008 (2007/10/03)
Treatment of γδ-unsaturated ketone O-acetyloximes with a catalytic amount of 1,5-naphthalenediol or hydroquinone, acetic acid, and 1,4-cyclohexadiene affords various dihydropyrrole and pyrrole derivatives via radical cyclization induced by one-electron reduction of the oximes.
Synthesis of pyrrole derivatives by palladium-catalyzed cyclization of γ,δ-unsaturated ketone o-pentafluorobenzoyloximes
Tsutsui, Hironori,Kitamura, Mitsuru,Narasaka, Koichi
, p. 1451 - 1460 (2007/10/03)
Various pyrrole derivatives are synthesized from γ,δ-unsaturated ketone O-pentafluorobenzoyloximes by treatment with catalytic amounts of Pd(PPh3)4 and triethylamine via alkylideneaminopalladium(II) intermediates generated by oxidative addition of the oximes to the Pd(0) complex.
A facile synthesis of 5-substituted 2-furyl-, 2-thienyl- and 2- pyrrolylacetates by cyclodehydration of γ-functionalized α,β-unsaturated ketones
Kawano, Tomikazu,Ogawa, Toni,Md. Islam, Saiful,Ueda, Ikuo
, p. 1279 - 1295 (2007/10/03)
Synthesis of 5-substituted 2-furyl-, 2-thienyl- and 2-pyrrolylacetates is achieved by acid-catalyzed cyclodehydration of γ-hydroxy (γ-acetylthio and γ-amino)-α,β-unsaturated ketones generated from ethyl 6-substituted 3- ethoxy-6-hydroxy-(6-acetylthio and 6-amino)hexa-2,4-dienoates which are easily accessible from α-functionalized carbonyl compounds and Wittig reagents.
Synthesis of pyrrole derivatives by the heck-type cyclization of γ,δ-unsaturated ketone O-pentafluorobenzoyloximes
Tsutsui, Hironori,Narasaka, Koichi
, p. 45 - 46 (2007/10/03)
Substituted pyrroles are synthesized from γδ-unsaturated ketone O-pentafluorobenzoyloximes by the intramolecular Heck-type amination of the olefinic moiety catalyzed by Pd(PPh3)4.
