Substituted aminopyrimidines are an important class of compounds, in part because they frequently show biological activity. Facilesynthesis of polysubstituted aminopyrimidines is highly desirable for the synthesis of screening libraries. We describe a route to 4,6‐diamino‐5‐alkoxypyrimidines via a SNAr‐alkylation‐SNAr sequence from readily available 4,6‐dichloro‐5‐methoxypyrimidine, which allows the
取代的氨基嘧啶是一类重要的化合物,部分原因是它们经常表现出生物活性。多取代氨基嘧啶的简便合成对于筛选文库的合成是非常理想的。我们描述了一种通过 S N Ar-烷基化-S N Ar 序列从容易获得的 4,6-二氯-5-甲氧基嘧啶合成 4,6-二氨基-5-烷氧基嘧啶的路线,这使得可以通过区域化学控制合成此类化合物。将这种方法扩展到带有氨基取代基的烷化剂,会产生意想不到的、在某些情况下是前所未有的产物,这些产物是由分子内 S N Ar 环化和随后的断裂产生的。

from stoichiometric waste products into catalysts and a new concept for catalytic phosphorus-based activation and nucleophilicsubstitution of alcohols has been validated. The present study has focused on a full exploration of the scope and limitations of phosphine oxide catalyzed chlorination reactions as well as the development of the analogous bromination reactions. Further mechanistic studies, including

The synthesis of rotaxanes derived from the syntheticpeptide macrocycles cyclo(l-ProGly)4 and cyclo(l-ProGly)5 and diammonium threads is described. [2]Rotaxanes are formed in good yields (56-63%), despite the disruption of internal amide-amide hydrogenbonding in the macrocycles.
