Synthetic studies towards (-)-lemonomycin, synthesis of fused tetracycles was written by Couturier, Cedric;Schlama, Thierry;Zhu, Jieping. And the article was included in Synlett in 2006.Category: quinuclidine This article mentions the following:

The asym. synthesis of 1,3-lactol-bridged tetrahydroisoquinolines I [R = SiMe₂CMe₃, CH₂Ph; R¹ = CH₂CH(CO₂Me)₂; R² = CO₂CH₂Ph] was developed. Subsequent cyclizations of I (R = SiMe₂CMe₃, CH₂Ph) under acidic conditions lead to the formation of a tricyclic enamides II [R = SiMe₂CMe₃, CH₂Ph; R¹ = CH₂CH(CO₂Me)₂; R² = CO₂CH₂Ph]. II [R = CH₂Ph, R¹ = CH₂CH(CO₂Me)₂, R² = CO₂CH₂Ph] was in turn converted to a tetracyclic compound III. In the experiment, the researchers used many compounds, for example, (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide (cas: 200132-54-3Category: quinuclidine).

The development of synthetic approaches for efficient construction of novel quinuclidine derivatives is of great significance. Traditionally, quinuclidine scaffolds can be constructed by second-order nucleophilic substitution (SN2) reaction or condensation reaction of piperidine derivatives. However, most of these reactions are racemic or chiral auxiliary-assisted processes.Category: quinuclidine

A Ruthenium(II) Tris(bipyridyl) Amino Acid: Synthesis and Direct Incorporation into an α-Helical Peptide by Solid-Phase Synthesis was written by Kise, Kenneth J. Jr.;Bowler, Bruce E.. And the article was included in Inorganic Chemistry in 2002.Safety of (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide This article mentions the following:

The synthesis of a ruthenium(II) tris(bipyridyl) amino acid is described along with its incorporation into a helix-forming peptide using standard solid-phase peptide synthesis methods. The phys. properties of the metalloamino acid sep. and in the context of the peptide are reported. The electrochem. potential, absorption spectrum, emission and excitation spectra, and emission lifetime data for the ruthenium(II) tris(bipyridyl) amino acid are similar to those of ruthenium(II) tris(bipyridine), indicating that the amino acid functionality introduced on one of the bipyridine rings does not strongly perturb the properties of the metal complex. The ruthenium(II) tris(bipyridyl) amino acid is amenable to direct incorporation into a synthetic peptide using solid-phase methods and BOC/benzyl chem. The 22 amino acid alanine-based peptide produced is 67% helical at 0° in aqueous buffer, as measured by CD spectroscopy. The 2,2,2-trifluoroethanol helix induction curve and the temperature dependence of the helicity are typical for alanine-based peptides. The Lifson-Roig helix propagation parameter, w, derived from CD and NMR-monitored kinetic hydrogen-deuterium exchange is 0.5 ± 0.1 at 0°, indicating a moderate helix propensity for this metalloamino acid. In the experiment, the researchers used many compounds, for example, (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide (cas: 200132-54-3Safety of (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide).

And the article was included in Journal of Organic Chemistry in 2011.Computed Properties of C37H37BrN2O This article mentions the following:

We describe a generalized approach to stereocontrolled synthesis of substituted cyclic hydroxamic acids (3-amino-1-hydroxy-3,4-dihydroquinolinones), e.g. I (R = F₃CO, MeO, Me, Cl), by selective reduction of substituted 2-nitrophenylalanine substrates. Compounds in this series have antibacterial properties and have also recently been reported as KAT II inhibitors. The key nitrophenyl alanine intermediates are prepared enantioselectively in excellent yield by phase transfer catalyzed alkylation of the corresponding nitrobenzyl bromides. The scope and limitations of the reductive cyclization transformation have been explored with attention to the effects of substitution pattern and electronics on reaction efficiency and byproduct formation. In addition, a novel activated trifluoroethyl ester cyclization strategy has been developed as an alternate approach to the most sterically demanding systems in this series. In the experiment, the researchers used many compounds, for example, (1S,2S,4S,5R)-2-((R)-(Allyloxy)(quinolin-4-yl)methyl)-1-(anthracen-9-ylmethyl)-5-vinylquinuclidin-1-ium bromide (cas: 200132-54-3Computed Properties of C37H37BrN2O).
