Methoxy-substituted centrohexaindanes through the fenestrane route.
Tetrahydroxyfenestrindane undergoes HPF6-catalyzed condensation with anisole, 2-methylanisole and the three dimethoxybenzenes to furnish several centrohexaindanes bearing oxyfunctionalization at the opposite ends of one of the three [2,2']-spirobiindane axes.
