The present disclosure relates to compounds of formula I that are useful as modulators of α7 nAChR, compositions comprising such compounds, and the use of such compounds for preventing, treating, or ameliorating disease, particularly disorders of the central nervous system such as cognitive impairments in Alzheimer's disease, Parkinson's disease, and schizophrenia, as well as for L-DOPA induced-dyskinesia and inflammation
Five 4,4'-bithiazole-based tetraarylenes were prepared and their photochromic behavior investigated. With their 1,3,5,7-octatetraene photoreactive backbone, they offer not only more available sites for further functionalizations, but also a novel design principle for the development of a new class of biphotochromes.

palladium-catalyzed C–Ncross-coupling methodology, high-throughput experimentation was used to identify a catalyst capable of fusing piperidine-based nucleophiles with five-membered (hetero)aromatic bromides. A decomposition pathway for the standard electrophile was found, and a base screen was used to identify conditions that suppress this undesired transformation. Building on this, systematic optimization using
A systematic study of the cross-coupling capability of the 4- and 5-positions of 2-phenylthiazoles and -oxazoles under Stille conditions is presented. The azoles were both applied as stannanes and as the halide component. The obtained results were compared regarding the position of the halide and Bu3Sn group. In order to establish a general reactivity platform for those heterocyclic systems, a broad variety of aromatic and heteroaromatic halides were coupled and some significant differences concerning the coupling properties of the investigated systems were observed.
