Enantioselective Syntheses of the Alkaloids <i>cis</i>-195A (Pumiliotoxin C) and <i>trans</i>-195A Based on Multiple Applications of Asymmetric Catalysis
Short enantio- and diastereoselective syntheses of the
decahydroquinoline
alkaloids <i>cis</i>- (pumiliotoxin C) and <i>trans</i>-<b>195A</b> are presented. Key steps are an enantioselective
iridium-catalyzed allylic amination, a Suzuki–Miyaura coupling,
a catalyst-controlled copper-catalyzed 1,4-addition, and a reductive
amination
Enantioselective Total Synthesis and Absolute Configuration of Apiosporic Acid
The first total synthesis of the polyketide apiosporic
acid is
presented. Key steps are a Julia–Kocienski olefination, a Suzuki–Miyaura
cross-coupling, and an intramolecular Diels–Alder reaction.
The absolute configuration of the natural product was determined
