Dimeric Cinchona alkaloids. [PDF]
Nature is full of dimeric alkaloids of various types from many plant families, some of them with interesting biological properties. However, dimeric Cinchona alkaloids were not isolated from any species but were products of designed partial chemical synthesis.

Electrochemical Behavior of Some Cinchona Alkaloids Using Screen-Printed Electrodes [PDF]
An effective deposition of a cinchonine layer on a platinum metal surface can be easily achieved through the cathodic reduction of a cinchonine hydrochloride methanolic solution at a controlled potential of −220 mV vs. the silver standard electrode (SSE).

Stereoselective α-Chlorination of β-Keto Esters in the Presence of Hybrid Amide-Based Cinchona Alkaloids as Catalysts. [PDF]
We report an enantioselective phase transfer α-chlorination of β-keto esters catalyzed by hybrid amide-based Cinchona derivatives. The chlorination process proceeds with proper quantitative yields (up to

New α- and β-cyclodextrin derivatives with cinchona alkaloids used in asymmetric organocatalytic reactions [PDF]
The preparation of new organocatalysts for asymmetric syntheses has become a key stage of enantioselective catalysis. In particular, the development of new cyclodextrin (CD)-based organocatalysts allowed to perform enantioselective reactions in water and
