Abstracttrans‐2‐Alkylaminocyclohexanols and trans‐2‐alkylaminocycloheptanols condense with formaldehyde to give perhydrocycloalkano[d][1,3]oxazoles, whereas trans‐2‐alkylaminocyclopentanols give rise to perhydrocyclopentano[f][1,3,5]dioxazepines. The two types of ring systems are characterized by differing proton‐proton geminal coupling constants and 13C NMR parameters.
