Abstract:

Floribundane A and Floribundane B are new iridoids recently isolated by de Mendoça and coworkers from barks and trunks of Hymenodictyon floribundum B. L. Rob. The trunk has been used on Angola’s folk medicine for the treatment of fever. Due to our interest to synthesize new lactones with promising biological activities and the absence of a total synthesis of this molecule, we started synthetic studies aiming the total synthesis of Floribundane B. Our retrosynthetic analysis has the hydroxylactone 1 as the key intermediate and this abstract reports our former results.
