Abstract The synthesis of quinuclidine‐3‐spiro‐5′‐oxazolidine‐2′,4′‐dione, quinuclidine‐3‐spiro‐5′‐hydantoin, and some 3′‐derivatives is described. Based on the data from 1 H and 13 C‐nmr spectra the structure of the above mentioned compounds is established. A relationship between second order effects in 13 C‐nmr spectra and H‐C‐C‐H dihedral angles is deduced.
