The absolute stereochemistry of tetronomycin (2), a novel acyltetronic acid ionophore, was confirmed by comparison of the degradation product 3 with the synthetic enantiomer 9 derived from L-rhamnose. The enantiomer 18 of the polyether subunit of 2 was synthesized by coupling 9 with tetrahydropyran portion 15 prepared from D-glucose.
