Herein, we report on the first enantioselective synthesis of the sparteine-type alkaloids virgidivarine (1) and virgiboidine (2). The stereoselective construction of the challenging dipiperidine core within 1 and 2 was realized by applying an intramo

The Rh-catalyzed cycloisomerization of new terpenoid derivatives featuring an O-tethered enyne unexpectedly leads to polycyclic derivatives containing an inner cyclopropane ring or a diene moiety, depending on the structure of the enyne, as observed
