Straightforward access toward previously unreported substituted, heterocyclic spiro[3.3]heptanes is disclosed. These spirocyclic systems may be considered as alternatives to 1,3-heteroatom-substituted cyclohexanes, which are otherwise insufficiently stable to allow their use in drug discovery. Conformational details are discussed on the basis of X-ray crystallographic structures.
