Abstract
The stereoselective total synthesis of rhoiptelol B, a diarylheptanoid isolated from
Rhoiptelea chiliantha
is described. The tetrahydropyran ring was constructed by using Prins cyclization. The key steps involved in this synthesis are Prins cyclization, Mistunobu inversion, cross metathesis, Sharpless asymmetric dihydroxylation, and hydrogenolysis.
