Synthetic studies of zoanthamine/norzoanthamine: Biogenetic-like one-step construction of the heterocyclic aminal core (CDEFG ring) from a monocyclic precursor

Biogenetic-like one-step construction of the pentacyclic aminal core of zoanthamine/norzoanthamine alkaloids was accomplished in high yield from the suitably protected monocyclic aminohydroxy diketocarboxylic acid 7 by heating in aqueous acetic acid.

Synthetic studies of zoanthamine/norzoanthamine alkaloids: Advanced intermediate for the heterocyclic aminal core

An advanced intermediate for the heterocyclic aminal core of zoanthamine/norzoanthamine alkaloids was prepared in an enantio and stereoselective manner. Contiguous quaternary chiral centers were selectively constructed utilizing a stereoselective cuprate addition to the readily available (+)-Wieland-Miescher ketone.
