Streptazolin is an antibiotic and antifungal substance isolated in 1981 from Streptomyces viridochromogenes.[1][2]
Because of its polymerisation tendency, it is not suitable for therapeutic use. 1,4-reduction of the conjugated diene gives dihydrostreptazolin which is stable, but has very limited microbial properties.<ref name=" name="Drautz" />
The first total synthesis of (racemic) streptazolin was achieved in 1985 with the aid of a modified Ferrier rearrangement.[3][4]
