Synthesis of a sterically congested diazirine: 2-azi-camphane

Tetrahedron Letters, 1996
Abstract The synthesis of 2-azi-camphane has been achieved despite the fact that the spirocyclic carbon center is sterically congested. Although the yield is somewhat low, the highly pure diazirine can be used as a precursor for the burgeoning class of sterically congested carbenes.

Camphane-based aminophosphine ligands for Pd-catalyzed asymmetric allylic alkylation

Tetrahedron: Asymmetry, 2013
Abstract A practical synthesis of new chiral aminophosphine ligands based on the camphane scaffold bearing alkoxy groups was accomplished. The application of these ligands in the Pd-catalyzed allylic alkylation of ( E )-1,3-diphenyl-2-propenyl acetate proceeded with excellent conversions and ee’s of up to 91%. Variation of the alkoxy substituents did

The configurations of the trans -Camphane-2,3-diols

Australian Journal of Chemistry, 1984
The originally postulated configurations of camphane-2- endo ,3 -exo - and -2- exo ,3- endo -diols, which were recently claimed to be incorrect, have been confirmed by the use of 13C n.m.r. spectroscopy and by the X-ray crystal structure analysis of the dibenzoate of camphane-2- endo ,3- exo -diol.

Resolution of diastereomeric flavonoid (1S)-(−)-camphanic acid esters via reversed-phase HPLC

Phytochemistry, 2007
Prenylflavonoids are an unique class of phytochemicals found in the inflorescences of the hop plant (Humulus lupulus). These flavonoids have demonstrated a wide range of biological activities, which may be influenced by their stereochemical configuration.

Über Tricyclol und seine Umwandlungen, besonders in 2.6‐Dioxy‐camphan

Chemische Berichte, 1947
AbstractAus Tricyclol, dessen Herstellungsverfahren wesentlich verbessert worden ist, entsteht bei der Einwirkung von Phosphortribromid nicht das gesuchte gesättigte Bromtricyclen, sondern 6‐Brom‐camphen. Seine Konstitution wurde bewiesen durch Überführung in die Grignard‐ Verbindung und Hydrolyse zum Camphen, das durch Umwandlung in Isoborneol bzw ...
