A total synthesis of the natural enantiomer of integerrimine (1), a twelve-membered dilactonic pyrrolizidine alkaloid of retronecine type has been achieved through the enantioselective synthesis and regioselective coupling of (+)-retronecine (4) and (+)-integerrinecic acid (methylthio)methyl ether (6).
