Harnessing cheminformatics for catalyst design I. Investigation into a general, asymmetric synthesis of cinchona alkaloid analogs towards asymmetric phase transfer II. Development of an enantioselective brønsted acid catalyzed four-component Ugi reaction
… catalyst activity. An asymmetric metalation of quinuclidine N–oxide and trapping of various aldehydes was explored. Quinuclidine was utilized as the bulk starting material. An improved synthesis of quinuclidine was developed through a Henbest modified Wolff-Kishner reduction of 3-quinuclidone. …

Zinc polysulfides as precursors to zinc sulfide and as group transfer reagents
… L to afford $\rm ZnS\sb6L\sb2$ (L = MeIm, quinuclidine). The pyridine analog, $\rm ZnS\sb6py\sb2$ also undergoes ligand substitution with TEEDA $(N,N,N\prime,N\prime$-tetraethylethylenediamine) and ($-$)-sparteine to afford $\rm ZnS\sb6$(TEEDA) and $\rm ZnS\sb6\{(-)$-sparteine$\};$ these …

Inclusion of Molybdenum into microporous and mesoporous materials
… that can retain more molybdenum compared to quinuclidine templated cloverite. The overall amount retained was lower than the amount retained in Y zeolites, although the cloverite pore size is larger than Y zeolite's, indicating a poorer interaction between cloverite and the molybdenum …

Characterisation of drug loaded insoluble polymeric matrices prepared by hot melt extrusion technology for drug delivery applications.
… an interaction between the N atom of the quinine quinuclidine moiety and the carboxcylic acid group -OH of the acid molecules occurred during salt formation. From this it was proposed that polymer drug interactions strongly influenced the drug solubility in the matrix which in turn had a …
