asymmetric total synthesis of the norsesquiterpenoid saniculamoid D, from a previously known pure chiral imide, with a longest linear sequence of seven steps. The key highlight of the synthesis is the formation of the bicyclo[3.1.0]hexane moiety through the Julia–Kocienski olefination and Hodgson cyclopropanation. Notably, the NMR spectra and specific rotation value of the synthesized structure did not agree
