Article abstract of DOI:10.1002/mrc.1270170408

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