Synthesis of Diels-Alder adducts of the quinolizidine alkaloids N-methylcytisine, (-)-leontidine, and (-)-thermopsine with N-phenylmaleimide

The Diels-Alder adducts of the quinolizidine alkaloids N-methylcytisine, (-)-leontidine, and (-)-thermopsine with N-phenylmaleimide have been synthesized. The structures and absolute configurations of the new asymmetric centers of the products were determ

The Enantioselective Total Synthesis of Bisquinolizidine Alkaloids: A Modular “Inside-Out” Approach

Bisquinolizidine alkaloids are characterized by a chiral bispidine core (3,7-diazabicyclo[3.3.1]nonane) to which combinations of an α,N-fused 2-pyridone, an endo- or exo-α,N-annulated piperidin(on)e, and an exo-allyl substituent are attached. We developed a modular “inside-out” approach that permits access to most members of this class. Its applicability was proven in the asymmetric synthesis of 21 natural bisquinolizidine alkaloids, among them more than ten first enantioselective total syntheses. Key steps are the first successful preparation of both enantiomers of C2-symmetric 2,6-dioxobispidine by desymmetrization of a 2,4,6,8-tetraoxo precursor, the construction of the α,N-fused 2-pyridone by using an enamine-bromoacrylic acid strategy, and the installation of endo- or, optionally, exo-annulated piperidin(on)es.

Synthesis and specific nootropic activity of (-)-cytisine derivatives with carbamide and thiocarbamide moieties in their structure

N-(methylcytisinyl)-N-substituted ureas, N-substituted cytisine-12- carbamides, and cytisine-12- thiocarbamide were prepared by reaction of (-)-cytisine with urea and thiourea and of (-)-cytisine and its 12-N-methyl-3-amino derivative with isocyanates. Their specific nootropic activity was studied in vivo. The therapeutic index was determined for the lead compound. Promising candidates for further pharmacological testing were found.
