4-α-(or β)-p-Chlorobenzoyloxy-1-azaadamantane hydrochloride have been synthesized and studied by 1H and 13C nmr spectroscopy, and the crystal structure of the α-epimer has been determined by X-ray diffraction. Each ring of the adamantane cage system is a nearly perfect chair, the substituted cyclohexane and piperidine rings, in endo and exo position respectively, having the biggest deviation. From the 1H and 13C nmr data, several stereoelectronic effects have been deduced. 相似文献
