complementary to uracil/thymine. These heterocycles, which have never before been reported or characterized, represent diaminopurine−uracil/thymine hybrids that, in two of the three cases, relate to previously reported heterocyclic hybrids of G and C. All three heterocycles crystallized to afford the first X-ray crystal structures of self-complementary heterocycles capable of ADA−DAD pairing. The potential
具有确定的氢键接受和给定能力的杂环的高产率合成提供了自组装结构的设计和对生物靶标的特异性识别。本文中,我们报告了三种自我互补的尿嘧啶/胸腺嘧啶衍生物的合成和固态结构,其中每一种都呈现出与腺嘌呤固有互补的标准ADA面孔和与尿嘧啶/胸腺嘧啶互补的合成附加DAD面孔。这些杂环从未被报道过或表征过,它们代表了二氨基嘌呤-尿嘧啶/胸腺嘧啶杂种,在三种情况中的两种中,它们与先前报道的G和C杂环杂种有关。所有三个杂环结晶后可提供第一张X射线能够实现ADA-DAD配对的自互补杂环的晶体结构。
