construction of small heterocycles using solid-phase chemistry is usually done through the use of a polar group to attach the compounds to the resin. These polar functionalities invariably become part of the structure and eventually limit the structure-activity relationships derived from these compounds. We have identified a method for overcoming some of these limitations. A sulfur-based linker has been
使用固相化学方法构建小的杂环通常是通过使用极性基团将化合物连接到树脂上来完成的。这些极性官能团始终成为结构的一部分,并最终限制了衍生自这些化合物的构效关系。我们已经找到一种克服这些局限性的方法。已经鉴定出基于硫的连接基,其不仅可以用作小杂环的连接点,而且还可以用作将进一步的多样性引入分子的手段。接头保持惰性,直到被氧化“激活”为止。然后可以使用有限量的亲核试剂从树脂上裂解该分子并将另外的多样性引入该分子中。
