Militarinone C and fumosorinone A, 3-oligoenoyltetramic acids produced by insect pathogenic fungi, were synthesized for the first time. The pyrrolidine-2,4-dione ring was closed through a late-stage Dieckmann condensation of N-(β-ketoacyl) derivatives of tyrosine, obtained by its acylation with either thioesters or Meldrum's acid derivatives bearing the all-trans-polyene side chain. The latter was built up from (S)-citronellol via an Evans methylation and Wittig or HWE olefinations.

The first total synthesis of martefragin A, a potent inhibitor of lipid peroxidation isolated from sea alga, has been accomplished and the absolute configurations of two stereogenic centers were determined. Synthetic martefragin A, its stereo isomers, and some analogs showed strong inhibitory activity against lipid peroxidation rat liver microsome.
