✦ Synopsis
The conformation of 2,4-dioxabicyclo[3.3.l]nonane was investigated with the use of lH NMR spectroscopy. From the coupling constants, the Nuclear Overhauser Effects and the T1-relaxation times it was concluded that this compound occurs predominantly in the bc conformation.

Three dimethyl-and one trimethyl-2.4dioxabicyclo[3.3.1 Inonanes were prepared and their configurations and conformations were determined by means of multinuclear high-field NMR spectroscopy. Even at 400 MHz the proton spectra were so degenerate that several 2D experiments and, also, deuterium NMR ha
