An enantio- and diastereoselective synthesis of the C17–C29 fragment of amphidinolide N, an extremely potent macrocyclic cytotoxin of marine origin, has been accomplished from a known olefinic ester by a 10-step sequence that involves a ring opening of a chiral epoxide with a dithiane derivative to construct the full carbon skeleton, a highly diastereoselective reduction of a β-hydroxy ketone intermediate to install the C21 asymmetric center, and a one-pot Sharpless AD/cyclization sequence to form a trans-substituted tetrahydrofuran ring system.
