An unexpected cascade transformation of aminonaphthoquinones with N-substituents bearing a p-methoxybenzyl ether into bridged-ring-fused naphthalenone derivatives is reported. This cascade transformation was initiated by a catalytic amount of Zn(OTf)2 and involved with subsequent functional group migration and cyclization. The process proceeded through the cleavage of two bonds and the formation of
