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 antimicrobial properties.[3]

The first total synthesis of (racemic) streptazolin was achieved in 1985 with the aid of a modified Ferrier rearrangement.[4][5]
