title: Short and efficient route to the fully functionalized polar core of scyphostatin.
abstract: [reaction: see text]. Diastereoselective oxidative dearomatization of benzopyran 5 to the corresponding p-quinol 9b allows a fast, efficient, and versatile entry to scyphostatin's polar epoxycyclohexenone moiety as demonstrated by the preparation of its palmitoyl analogue 16 (R = (CH2)14CH3).
