摘要
We describe herein the atroposelective formal synthesis of (-)-steganone, a parent member of Steganotaenia araliacea dibenzocyclooctadiene lignan lactones. Our synthesis features an atropodiastereoselective biaryl Suzuki-Miyaura cross-coupling reaction with de up to 99% using as a chiral auxiliary an enantiopure and efficiently converted beta-hydroxy sulfoxide derivative.
