摘要:
Starting from the commercially available D-glucal (2), the naturally Occurring alpha,beta -unsaturated delta -lactone argentilactone (1a) has been synthesized. The important step is the configuration inversion at C-6 by the Mitsunobu reaction following the sugar-non-sugar-sugar strategy. The synthetic argentilactone has been tested against Leishmania mexicana for bioactivity. (C) 2001 Elsevier Science Ltd. All rights reserved.
