Intramolecular Organocatalytic [3+2] Dipolar Cycloaddition: Stereospecific Cycloaddition and the Total Synthesis of (±)‐Hirsutene

Abstract

Ein Versuchsgelände für Cyclopentanellierungen: Der Triquinan-Naturstoff Hirsuten war das Fernziel bei der Anwendung einer intramolekularen organokatalytischen [3+2]-Cycloaddition des 1,7-Enins (E)-1. Die Cycloaddition verläuft stereospezifisch: (Z)-1 liefert das entsprechende epimere Diquinan.
