An efficient enantioselective synthesis of the spiro tetrahydroisoquinoline unit in ecteinascidin 743 is described, employing (+)-tetrahydrocarvone as a readily available and recoverable chiral auxiliary. The synthetic sequence involves a triply-convergent stereoselective bisannulation to construct the tetrahydroisoquinoline framework within 2.
