Convenient Synthesis of Pulchella-lactam, a CD45 Protein Tyrosine Phosphatase Inhibitor from the Marine Fungus Corollospora pulchella, and Its Related Compounds
Jatropham, (R)-(-)-5-hydroxy-3-methyl-3-pyrrolin-2-one, is synthesized in three steps from citraconic anhydride. Highly regioselective reduction of citraconimide gives racemic jatropham in high yield. Kinetic resolution of racemic jatropham using lipase is also described. (C) 1999 Elsevier Science Ltd.
