    Synthesis and crystal structures of iron(II) dichloride complexes with α-isosparteine, β-isosparteine and 2-methylsparteine
    摘要:
    Tetrahedrally distorted complexes of alpha-isosparteine, beta-isosparteine and 2-methylsparteine with FeCl2 have been synthesised. Crystal structures of these complexes are reported and compared with the structure of (-)-sparteine analogue. Coordination to Fe(II) center in beta-isosparteine and 2-methylsparteine brings about an inversion at the N16 nitrogen and change in configuration at the ring junction from trans to cis, accompanied by a change in the C-ring conformation from boat to chair. The all-chair alpha-isosparteine skeleton remains unchanged upon complexation. Structural parameters of the complexes are investigated using Becke three-parameter hybrid exchange functional combined with the Lee-Yang-Parr correlation functional (B3LYP) with 6-31G and 6-311G basis sets applied for geometry optimizations.

  • Structural Features and Reactivity of (Sparteine)PdCl<sub>2</sub>: A Model for Selectivity in the Oxidative Kinetic Resolution of Secondary Alcohols
    作者:Raissa M. Trend、Brian M. Stoltz
    DOI:10.1021/ja804955e
    日期:2008.11.26
    The chiral ligand (-)-sparteine and PdCl(2) catalyze the enantioselective oxidation of secondary alcohols to ketones and thus effect a kinetic resolution. The structural features of sparteine that led to the selectivity observed in the reaction were not clear. Substitution experiments with pyridine derivatives and structural studies of the complexes generated were carried out on (sparteine)PdCl(2)

    Bisimide 16 was generated from malonate via acid promoted cyclization of the Knoevenagel condensation adduct 1,1,3,3-propanetetracarboxamide. (+/-)-alpha-Isosparteine (dl-2) was elaborated from 16 in 28% overall yield by a two-directional synthetic sequence composed of four reactions: double addition of allylmagnesium bromide, ring-closing olefin metathesis (RCM), hydrogenation, and borane mediated reduction

    日期:2018.2.23
    Bisquinolizidine alkaloids are characterized by a chiral bispidine core (3,7‐diazabicyclo[3.3.1]nonane) to which combinations of an α,N‐fused 2‐pyridone, an endo‐ or exo‐α,N‐annulated piperidin(on)e, and an exo‐allyl substituent are attached. We developed a modular “inside‐out” approach that permits access to most members of this class. Its applicability was proven in the asymmetric synthesis of 21 natural

  • Oxidative Deamination of Tetrahydroanabasine with <i>o</i>-Quinones:  An Easy Entry to Lupinine, Sparteine, and Anabasine
    作者:Martin J. Wanner、Gerrit-Jan Koomen
    DOI:10.1021/jo9602130
    日期:1996.1.1
    A mild oxidative deamination reaction of tetrahydroanabasine O-methyloxime 17 is described, making use of an o-quinone that is based on topaquinone (TPQ, 11), the cofactor that is present in copper-containing amine oxidases, In situ ring closure of the oxidation product produced double-functionalized quinolizidine 5, containing an enamine functionality with excellent reactivity, From this quinolizidine 5 a variety of biogenetically related lupin alkaloids were prepared: lupinine (7) and aminolupinane (8) via reductive sequences and sparteine (9) via a condensation reaction with dehydropiperidine 1. The configurationally more favorable trans isomers epilupinine (25) and beta-isosparteine (10) were formed when more drastic reaction conditions were used for oxime hydrolysis, Anabasine (4) and a new 5-piperidylanabasine derivative 6 were formed by an unexpected acid catalyzed ring transformation reaction, whereby the pyridine ring was formed via oxime-induced aromatization. The stereochemistry of the reaction products and the biogenetic implications are discussed.
