The structure elucidation of a novel pentadepsipeptide 1, which revealed unprecedented metabolic correlations and was isolated from Phoma lingam, is described.

anoic acid] is the host-selective phytotoxin produced by the fungus [Leptosphaeria maculans (Desm.) Ces. etde Not., asexual stage Phoma lingam (Tode ex Fr.) Desm.] which causes blackleg disease (a devastating disease of several economically important brassica crops). Efficient total syntheses of phomalide, its (Z)-isomer isophomalide, and the two dihydro analogues [(R)-dihydrophomalide and (S)-dihydrophomalide]
