Stereocontrolled synthesis of kelsoene by the homo-Favorskii rearrangement

(graph presented) (±)-Kelsoene (4) has been synthesized from 2,5-dihydroanisole in 16 steps in 12.5% overall yield. The key step involves a base-catalyzed reaction of γ-keto tosylate (5), which effects a homo-Favorskii rearrangement to 16 as well as the c
