Enantioselective Synthesis of (+)-Peganumine A

Journal of the American Chemical Society, 2016
A gram-scale enantioselective total synthesis of (+)-peganumine A was accomplished in 7 steps from commercially available 6-methoxytryptamine. Key steps included (a) a Liebeskind-Srogl cross-coupling; (b) a one-pot construction of the tetracyclic skeleton from an ω-isocyano-γ-oxo-aldehyde via a sequence of an unprecedented C-C bond forming ...

Enantioselective Total Synthesis of Cylindramide.

ChemInform, 2005
Key steps in the convergent enantioselective synthesis of the cytotoxic natural product cylindramide are tandem Michael addn./electrophilic trapping reactions, Sonogashira coupling, Julia-Kocienski olefination, and macrocyclization. For example, the Sonogashira coupling of pentalene I with iodoacrylate II followed by Julia-Kocienski olefination with ...

Enantioselective Total Synthesis of (−)‐Terengganensine A

Angewandte Chemie, 2016
AbstractA seven‐step enantioselective total synthesis of (−)‐terengganensine A, a complex heptacyclic monoterpene indole alkaloid, was accomplished. Key steps included: a) Noyori's catalytic enantioselective transfer hydrogenation of the iminium salt to set up the absolute configuration at the C21 position; b) a highly diastereoselective C7 ...

Enantioselective Synthesis of (−)-Dendroprimine and Isomers

Journal of Natural Products, 2004
An enantioselective and diastereoselective synthesis of six 5,7-dimethylindolizidine isomers is described via an intramolecular cyclization that involves an allylsilyl nucleophilic group and an acyliminium ion. The first total synthesis of naturally occurring (-)-dendroprimine has been achieved in five steps.
