Abstract The mass spectra of the title compounds depend markedly on ring annulation. On ionization, the cis ‐annulated isomers lose alcohol and benzene regardless of the configuration of the alkoxyl. In the trans ‐annulated isomers, the fragmentation is governed by the configuration of both the aldehyde and the alkoxyl groups. The role of non‐bonding interactions is discussed.
