A highlystereoselective joint total synthesis of the potent polyketide macrolide antibiotics etnangien and etnangien methyl ester was accomplished by a convergent strategy and proceeds in 23 steps (longest linear sequence). Notable synthetic features include a sequence of highlystereoselective substrate-controlled aldolreactions to set the characteristic assembly of methyl- and hydroxyl-bearing
