Total Synthesis of Isodaphlongamine H by Iridium-Catalyzed Reductive [3 + 2] Cycloaddition of N-Hydroxylactam. [PDF]

Angew Chem Int Ed Engl
The total synthesis of isodaphlongamine H was accomplished by a lactam strategy. This strategy started with alkylation and N‐oxidation of a readily available chiral lactam. For the key functionalization of the amide carbonyl, an iridium‐catalyzed reductive [3 + 2] cycloaddition of the N‐hydroxylactam afforded the tricyclic isoxazolidine, which was ...

Overturning established chemoselectivities : selective reduction of arenes over malonates and cyanoacetates by photoactivated organic electron donors [PDF]

, 2013
The prevalence of metal-based reducing reagents, including metals, metal complexes, and metal salts, has produced an empirical order of reactivity that governs our approach to chemical synthesis.
