Tandem radical cyclization reactions, initiated at nitrogen, as an approach to the CDE-tricylic cores of certain post-secodine alkaloids
Banwell, Martin G.,Lupton, David W.
, p. 71 - 92 (2007/10/03)
-The nitrogen-radical precursors (10-15) have been prepared and subjected to reaction conditions expected to promote tandem radical cyclization sequences leading to the CDE-tricyclic frameworks associated with alkaloids such as vindoline (1) and ibophylli
Exploiting the palladium[0]-catalysed Ullmann cross-coupling reaction in natural products chemistry: Application to a total synthesis of the alkaloid (±)-aspidospermidine
Banwell, Martin G.,Lupton, David W.
, p. 213 - 215 (2007/10/03)
The application of Ullmann cross-coupling reaction for the synthesis of the alkaloid (±)-aspidospermidine was studied. The initial step associated with the second stage of the synthesis of aspidospermidine involved the Pd[0]-catalyzed Ullmann cross-coupli
Application of the palladium(0)-catalyzed ullmann cross-coupling reaction in a total synthesis of (±)-aspidospermidine and thus representing an approach to the lower hemisphere of the binary indole-indoline alkaloid vinblastine

As part of ongoing studies directed towards the construction of the anti-cancer agent vinblastine (1), the related but structurally less complex natural product aspidospermidine (3) has been synthesized. Two approaches to target 3 were pursued. In the fir

Compounds of formula (i) and of formula (ii) wherein the symbols have the meaning disclosed in the specification, specifically or selectively modulate α2B and/or α2C adrenergic receptors in preference over α2A adrenergic receptors, and as such are useful for alleviating chronic pain and allodynia and have no or only minimal cardivascular and/or sedatory activity.
Chemo-enzymatic preparation of optically active endo- bicyclo[4.1.0]heptan-2-ols
Barnier, Jean-Pierre,Morisson, Veronique,Volle, Isabelle,Blanco, Luis
, p. 1107 - 1117 (2007/10/03)
Resolutions of endo-bicyclo[4.1.O]heptan-2-ols were achieved by acylation in the presence of lipase from Candida antarctica (Novozym). The (1S,2R,6R) enantiomers reacted faster and the enantiomeric ratios were between 60 and 800 for the 6-substituted bicycloalkanols.
Lipase-mediated Resolution of 2-Cyclohexen-1-ols as Chiral Building Blocks en route to Eburnane Alkaloids
Carrea, Giacomo,Danieli, Bruno,Palmisano, Giovanni,Riva, Sergio,Santagostino, Marco
, p. 775 - 784 (2007/10/02)
Lipase catalyzed esterification of several 2-cyclohexen-1-ols proceeds with excellent enantioselectivity leading to (S)-enantiomers as promising chiral building blocks en route to eburnane alkaloids.
Oxidation by Cobalt(III) Acetate. Part 7. Regioselective Synthesis of Substituted Cyclohexenyl Acetates
Hirano, Masao,Morimoto, Takashi
, p. 1105 - 1108 (2007/10/02)
The oxidation of alkylcyclohexenes with cobalt(III) acetate has been studied in acetic acid under nitrogen. 1-Alkylcyclohexenes gave exclusively the corresponding 3-acetoxy-1-alkylcyclohexenes in good yields.Similarly, 3- and 4-methylcyclohexene afforded 3-acetoxy-6- and -5-methylcyclohexene, respectively, in suprising high selectivities.In all cases, the position α to the alkyl group was completely or largely insensitive to CoIII.The results can be explained in terms of steric hindrance of the alkyl group which limits the attack of CoIII at a hindered site.
