Abstract

A new tetrahydropyran scaffold has been efficiently prepared by Prins reaction between hepta-1,6-dien-4-ol and benzaldehyde. Subsequent functionalizations were further achieved by Mitsunobu reaction and/or by the way of cross-metathesis/Wacker oxidation sequence to deliver diospongin A analogues.
