## Abstract Some bridgehead nitrogen compounds possessing the CH(Me)โ€bridgehead N๏ฃฟC(O) system have been synthesised and their configurations assigned. The chemical shifts of the proton geminal to the methyl group provides evidence for the existence of a deformed chair conformation for the methyl su
