| Abstract: | trans-2-Alkylaminocyclohexanols and trans-2-alkylaminocycloheptanols condense with formaldehyde to give perhydrocycloalkanod]1,3]oxazoles, whereas trans-2-alkylaminocyclopentanols give rise to perhydrocyclopentanof]1,3,5]dioxazepines. The two types of ring systems are characterized by differing proton-proton geminal coupling constants and 13C NMR parameters. |
