title: Synthetic Study on Naphthospironone A: Construction of Benzobicyclo[3.2.1]octene Skeleton with Oxaspirocycle.
abstract: In connection with the total synthesis of naphthospironone A, a model study has revealed a promising approach to construct a benzobicyclo[3.2.1]octene skeleton possessing an oxaspirocycle by employing an intramolecular aldol cyclization.
