Efficient stereospecific synthesis of (S,S)-3-methoxy-4-methylaminopyrrolidine
摘要:
Efficient stereospecific synthesis of (S,S)-3-methoxy-4-methylaminopyrrolidine, an important intermediate for a novel quinolone antitumor agent AG-7352 is presented. Starting from either D- Or L-tartaric acid, a stereospecific synthesis of the chiral pyrrolidine was achieved via two S(N)2 displacement reactions. From the results of this synthetic study, the absolute structure of AG-7352 was chemically determined. (C) 2001 Elsevier Science Ltd. All rights reserved.
