Abstract
A late-stage photoisomerization/cyclization union tactic, in conjunction with Type I Anion Relay Chemistry (ARC), permits enantioselective total syntheses and then biological evaluation of (+)-peniciketals A and B. The photochemical protocol was further showcased by an efficient three-step construction of the architecturally complex polycyclic skeleton found in (-)-diocollettines A. The mechanism and diastereose-lectivity of the photochemical protocol have also been explored by both experiment and density functional theory calculations.Keywords
