乙炔连接的萘啶-苯胺共轭分子是二氯甲烷中癸基鸟嘌呤和水中鸟苷单磷酸(K ass = 16 000 M –1)的选择性传感器。2-乙酰氨基-1,8-萘啶部分与鸟嘌呤结合在DAA-ADD中,为氢键结合的三重基序。苯胺部分增强了给电子作用,对取代基进行了调节以获得额外的氢键,π-π堆积和静电相互作用。提出的结合模式得到Job图,ESI-MS,1 H NMR,UV-vis和荧光光谱分析的支持。

palladium‐catalyzed carbene insertion into C(sp3)−H bonds leading to pyrrolidines was developed. The coupling reaction can be catalyzed by both Pd0 and PdII, is regioselective, and shows a broad functional group tolerance. This reaction is the first example of palladium‐catalyzed C(sp3)−C(sp3) bond assembly starting from diazocarbonyl compounds. DFT calculations revealed that this direct C(sp3)−H bond functionalization
The gold standard: A gold‐catalyzed cascadereaction sequence for the preparation of polycyclicfusedindole cores exploits the ready availability and chemical flexibility of propargylic alcohols. The desired tri‐ or tetracyclic compounds are obtained in good yields with water as the only stoichiometric by‐product.
