Abstract
[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 potent antitumor 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 vinyl anion addition to generate the C(8,9) trisubstituted olefin incorporating stereogenicity at C(7). Alkylation with a model epoxide demonstrates that (-)-3 is a competent dithiane for further elaboration of the macrolide skeleton.
