Biomimetic-inspired synthesis of sporochartines through Diels–Alder reaction between enantiopure (−)-sporothriolide and (+)-trienylfuranol A

A reaction between synthesized enantiopure (+)-trienylfuranol A and cultivated (−)-sporothriolide allowed us to confirm that the spiranic backbones of sporochartines are formed by a [4 + 2] cycloaddition reaction.
