Synthesis of new quinuclidine derivatives via Pd-mediated cross-coupling and cross-benzannulation reactions
Autor: Carsten Thöne, Manfred Fild, Stefania Tötös, Ion Grosu
Publikováno v: Tetrahedron. 65:6226-6235
New functionalized quinuclidines were prepared via palladium-catalyzed addition reactions of terminal alkynes (donors) to internal alkynes (acceptors). The enantiopure terminal alkynes were derivatives of quincoridine and quincorine, two semi-natural

Synthetic and Structural Studies of Pd II and Pt II Complexes with Quincorine and Quincoridine Derivatives
Autor: Manfred Fild, Carsten Thöne, Stefania Tötös
Publikováno v: European Journal of Inorganic Chemistry. 2004:749-761
A series of PdII-quincorine and -quincoridine complexes in which the ligands are coordinated through N,O-donor atoms have been synthesised, and their structural features determined by X-ray crystallography. Additionally, new chiral tetradentate N,P-l
