A highly enantioselective oxidative dearomatization of naphthols with quinones catalyzed by a chiral spirocyclic phosphoric acid is described. The strategy provides concise access to enantioenriched cyclohexadienones with a quinone moiety. Remarkably, the obtained products could be easily transformed to a potentially useful dihydronaphtho[2,1-b]benzofuran scaffold.
描述了手性螺环磷酸催化的萘醌对苯酚的高度对映选择性氧化脱芳香化反应。该策略为具有醌部分的对映体富集的环己二酮提供了简洁的途径。值得注意的是,所获得的产物可以容易地转化为潜在有用的二氢萘[2,1- b ]苯并呋喃支架。
