  摘要：

  A series of new selective, high affinity A(1)-AdoR agonists is reported. Compound 23 that incorporated a carboxylic acid functionality in the 4-position of the pyrazole ring displayed K-iL value of 1 nM for the A(1)-AdoR and > 5000-fold selectivity over the A(3) and A(2A)-AdoRs. In addition, compound 19 that incorporated a carboxamide functionality in the 4-position of the pyrazole ring displayed subnanomolar affinity for the A(1)-AdoR (K-iL = 0.6 nM) and > 600-fold selectivity over the A(3) and A(2A)-AdoRs.

• CuI Controlled C–C and C–N Bond Formation of Heteroaromatics through C(sp³)–H Activation

  A new method for C–C and C–N bond formation of heteroaromatics and C(sp3)–H alkanes was developed with high regioselectivity. The reaction occurred on C8 to give 8-cylcoakylpurines by C–C bond formation only promoted by tBuOOtBu, while it occurred on the amino group to give N6-alkylated purines by C–N bond formation when 2 equiv of CuI were added. A reaction mechanism was also proposed based on our

  具有高区域选择性的杂芳烃和C（sp 3）-H烷烃的C–C和C–N键形成的新方法得到了发展。该反应发生在C8上，仅通过t BuOO t Bu促进了通过C–C键形成的8烷基甲酰基嘌呤，而当氨基当上，当2当量的CuI为2时，通过C–N键的形成产生了N 6烷基化的嘌呤。添加。根据我们的初步实验数据，还提出了一种反应机理。
