The formaltotalsynthesis of the antitubercularagenterogorgiaene was achieved in 12 steps by using a protectinggroupfree strategy. The synthesis involves an enamine-mediated 1,4-addition, an aldol condensation, dehydrogenation, Wittig olefination, intramolecular Friedel–Crafts cyclization, TEMPO-BAIB-mediated oxidation, and Evans auxiliary based diastereoselective methylation.
