A new method has been developed for the stereoselective construction of the AB rings of the
quinolizidine skeleton of matrine-type alkaloids with a cis-cis stereochemistry. The key …

We report a highly diastereoselective approach for the synthesis of the pentacyclic indole
core of the manadomanzamine alkaloid skeleton, with complete control over the relative and …

Closure of the six-membered C ring of pentacyclic mavacurine-type alkaloids from suitably
substituted tetracyclic substructures embodying rings ABDE of these alkaloids, either by …
