The Ascent of Supramolecular Polymers and Gels in Asymmetric Catalysis

Chemistry – A European Journal, Accepted Article.
Supramolecular polymers and gels, formed by the spontaneous assemblies of small molecules through various types of non‐covalent interactions, are attractive materials for many applications. Their modularity also offers many opportunities in asymmetric catalysis, that have been tackled in the last two decades and more intensively in the last one.

Development of CPA‐Catalyzed β‐Selective Reductive Amination of Cardenolides for the Synthesis and Biological Evaluation of Hydrolytically Stable Analogs

Chemistry – A European Journal, EarlyView.
We describe a new method to produce hydrolytically stable cardiotonic steroids using a CPA‐controlled diastereoselective reductive amination of cardenolide aglycones. The oleandrin and digitoxigenin analogs exhibited promising activity against various cancer cell lines in the NCI‐60 screen.
