摘要：

Enantiomeric pairs of the ABE ring system (5 and ent-5) and its analogues (6, ent-6, 7, and ent-7) of quinocarcin (1), a prominent antitumor antibiotic, were synthesized in >95% ee with an aim to elucidate structure-activity relationships of 1. The key step of the synthesis includes novel diastereoselective reduction of 3,4-dihydroisoquinoline derivatives 25 and ent-25, wherein each enantiomer of 4-O-benzyl-2,3-O-isopropylidene-threose (I and ent-I) is employed as a chiral auxiliary.
