摘要

Chaetomellic anhydrides A and B have been recently isolated1 from Chaetomella acutiseta, and their dianionic forms are potent and highly specific inhibitors of ras farnesyl-protein transferase. The provision of facile synthetic approaches to this bioactive natural product, Chaetomellic acid A anhydride (tetradecylmethylmaleic anhydride, 1e), is a task of current interest. 2-9 Seven alternate syntheses of 1e, including two from our group, 6, 7 have ...
