Two conformations of the cis-cyclohexano-8-crown-3 molecule were detected at 185 K. From relative 13 C NMR peak area measurements, the conformation with the O-CH 2 -O unit equatorial was found to be favoured by 4.4 Ε‘ 0.4 kJ mol 1 . In the spectrum of the minor conformer at low temperature, a 9.6 ppm

A series of esters derived from synand anti-2-methyl-2-azabicyclo [ 2.2.2 ] octan-5-ols were synthesized and studied by 1H, 13C and 2D NMR spectroscopy. The crystal structure of 5-syn-(3,5-dichlorobenzoyloxy)-2-methyl-2azabicyclo [ 2.2.2 ] octane was determined by x-ray di β raction. The unambiguous
