Synthesis of the Tricyclo3,8>pentadecane (ABC) Ring System of Taxane Diterpenes
Romero, Miguel A.,Franco, Ruben Perez,Cruz-Almanza, Raymundo,Padilla, Fernando
, p. 3255 - 3258 (2007/10/02)
The synthesis of diketone 14 possessing the tricyclo3,8>pentadecane (ABC) taxane ring system is described.This concise approach employs a Wacker oxidation, intramolecular aldol condensation-dehydration, and a highly exo-stereoselective
2-Allylisourea as an Effective Agent for Direct α-Allylation of Ketone and Aldehyde Assisted by Palladium(0) under Neutral Conditions
Inoue, Yoshio,Toyofuku, Masanori,Taguchi, Masaaki,Okada, Shin-ichi,Hashimoto, Harukichi
, p. 885 - 892 (2007/10/02)
Direct α-allylation of a variety of ketones and aldehydes with 2-allylisourea took place in the presence of a catalytic amount of a palladium(0) complex under neutral and mild conditions.Scope and limitations of this novel method have been investigated.
Palladium-catalysed Asymmetric Allylations by a Chiral Allyl Ester; the Palladium Catalysis of (S)-Proline Allyl Ester Enamines
Hiroi, Kunio,Suya, Kyoko,Sato, Shuko
, p. 469 - 470 (2007/10/02)
The palladium-catalysed allylation of the chiral enamines (1a-d) followed by acidic hydrolysis, produced optically active 2-allylcyclohexanone (2); the catalysis of the chiral enamine (1a), derived from (S)-proline allyl ester, with tetrakis(triphenyl pho
NUCLEOPHILIC SUBSTITUTION REACTIONS OF ALLYLIC ESTERS CATALYSED BY PALLADIUM-GRAPHITE AND RELATED HETEROGENEOUS CATALYSTS
Boldrini, Gian Paolo,Savoia, Diego,Tagliavini, Emilio,Trombini, Claudio,Umani-Ronchi, Achille
, p. 97 - 106 (2007/10/02)
Highly dispersed palladium on graphite (Pd/Gr), carbon (Pd/C) and alumina (Pd/Al2O3) have been employed as catalysts in substitution reactions of allylic esters with nucleophiles such as benzenesulfinate and diethyl malonate anions, and 1-(1-cyclohexen-1-yl)pyrrolidine.
DIRECT Α-ALLYLATION OF KETONES WITH O-ALLYLISOUREA CATALYZED BY PALLADIUM(0)
Inoue, Yoshio,Toyofuku, Masanori,Hashimoto, Harukichi
, p. 1227 - 1228 (2007/10/02)
Direct α-allylation of ketones catalyzed by a palladium(0)-diphosphine system took place employing O-allylisourea as the allylating reagent under neutral conditions ar room temperature in DMF.
SYNTHESIS OF γ,δ-UNSATURATED KETONES BY THE INTRAMOLECULAR DECARBOXYLATIVE ALLYLATION OF ALLYL β-KETO CARBOXYLATES AND ALKENYL ALLYL CARBONATES CATALYZED BY MOLYBDENUM, NICKEL, AND RHODIUM COMPLEXES
Tsuji, Jiro,Minami, Ichiro,Shimizu, Isao
, p. 1721 - 1724 (2007/10/02)
Allyl β-keto carboxylates and alkenyl allyl carbonates were converted to γ,δ-unsaturated ketones by the intramolecular decarboxylative allylation catalyzed by molybdenum, nickel, and rhodium complexes.
