A new antifungal (E)-β-methoxyacrylate, noroudemansin A (1), wasisolated from cultures ofPterulasp. 82168. Its biological activities were investigated and compared with oudemansin A. The structure was elucidated by spectroscopic methods. Three semisynthetic noroudeman- sin A derivatives were synthesized from the natural product.
