A new strategy for enantioselective assembly of the trisubstituted tetrahydrofuran ring has been established for synthesis of the C1–C12 acid fragment of amphidinolide T series marinemacrolides. The key steps involve the SmI2-mediated highly enantioselective reductive coupling of an aldehyde with the (1S,2R)-N-methylephedrine-derived crotonate to form the cis-3,4-disubstituted γ-butyrolactone and the
