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.
公开了对先前未报告的取代的杂环螺[3.3]
庚烷的直接访问。这些螺环系统可以被认为是1,3-杂原子取代的
环己烷的替代物,否则其稳定性不足以使其用于药物开发。构象细节在X射线晶体学结构的基础上进行了讨论。
