The Total Synthesis of (−)-Scabrolide A [PDF]
Journal of the American Chemical Society, 2020 The first total synthesis of the norcembranoid diterpenoid scabrolide A is disclosed. The route begins with the synthesis of two chiral pool-derived fragments, which undergo a convergent coupling to expediently introduce all 19 carbon atoms of the natural product.

Total Synthesis of (+)‐Cornexistin [PDF]
Angewandte Chemie, 2020 AbstractHerein, we describe the first total synthesis of (+)‐cornexistin as well as its 8‐epi‐isomer starting from malic acid. The robust and scalable route features a Nozaki–Hiyama–Kishi reaction, an auxiliary‐controlled syn‐Evans‐aldol reaction, and a highly efficient intramolecular alkylation to form the nine‐membered carbocycle. The delicate maleic

Total Synthesis of (+)‐Epiquinamide. [PDF]
ChemInform, 2005 The stereoselective total synthesis of the novel quinolizidine alkaloid (+)-epiquinamide is presented, starting from the amino acid l-allysine ethylene acetal. Key steps in the synthesis involved a highly diastereoselective N-acyliminium ion allylation and a ring-closing metathesis reaction to provide the bicyclic skeleton. [reaction: see text]

Total synthesis of (±)-chamobtusin A [PDF]
Chemical Communications, 2011 The total synthesis of chamobtusin A, the first diterpenoid alkaloid isolated from the whole Pinales, is described. Key features of the synthesis include a stereoselective intramolecular Michael addition to install a key stereocenter and an oxidative manipulation to prepare a 2H-pyrrole ring.

Total Synthesis of (−)-Reveromycin A [PDF]
Organic Letters, 2004 The asymmetric total synthesis of (-)-reveromycin A is described. The key steps involved a Lewis acid catalyzed inverse electron demand hetero-Diels-Alder reaction followed by hydroboration/oxidation to afford the spiroketal core 4 in a highly stereoselective manner and introduction of the C18 hemisuccinate by high-pressure acylation.
