[formula: see text] In this Letter we describe a synthetic strategy and an efficient assembly of a common C(1)-C(11) subtarget, (-)-3, for (+)-tedanolide (1) and (+)-13-deoxytedanolide (2), architecturally complex marine macrolides displaying potentantitumor activity. Key elements of the synthesis include two iterations of the Evans aldol protocol to construct the C(1)-C(6) moiety and a stereocontrolled
