A Divergent Approach to the Diastereoselective Synthesis of Several Ant-Associated Iridoids
The ant-associated iridoids nepetalactol, actinidine, dolichodial, isoiridomyrmecin, and dihydronepetalactone were prepared from citronellal using a divergent approach. Key features include a three-step synthesis of the individual antipodes of actinidine by a novel tandem cycloaddition/pyridine formation and a facile diastereoselective synthesis of both enantiomers of dolichodial.
