Racemic synthesis of the new antibiotic tetramic acid reutericyclin
The synthesis of the new bacteriocidal compound reutericyclin, 3-acetyl-1-(2-trans-decenoyl)-2-hydroxy-5-isobutyl-Delta(2)-pyrrolin-4-one, is performed by coupling of N-(2-trans-decenoyl)-L-leucine to Meldrum’s acid followed by cyclization. The resulting N-acylated tetramic acid is directly C-acetylated in position 3. HPLC-purification on RP-C-18 gave racemic reutericyclin in high purity. 2D-NMR and FT-ICR-MS data are identical with those of natural reutericyclin.
