Abstract
Synthetic study toward iridoid 1 with anti-obese activity was performed by utilizing palladium-catalyzed cycloalkenylation reaction, Pd/C-catalyzed debenzylation reaction without hydrogenation and/or isomerization of alkene moiety, and the two-step, one-pot cyclization of diol as key steps.
