Abstract: Human tolllike receptor (hTLR)8 is expressed in myeloid dendritic cells, monocytes, and monocytederived dendritic cells. Engagement by TLR8 agonists evokes a distinct cytokine profile which favors the development of type 1 helper T cells. Focused exploration of structureactivity relationships in the imidazoquinolines has led to the identification of several novel human TLR8specific agonists. The synthetic procedures for bestinclass analogues encompassing four chemotypes are described.

This regioselective C–H functionalization provides a wide range of C-3 sulfonylmethyl indoles with upto 90% yields. Here, rongalite functions as a C1 unit source and a single electron donor. The use of inexpensive rongalite (ca. $0.03 per 1 g), mild reaction conditions and gram-scale synthesis are some of the key features of this methodology.

This regioselective C−H functionalization provides a wide range of heterodiarylmethanes of imidazo[1,2-a]pyridines and imidazo[2,1-b]thiazole. Here, rongalite plays a crucial role in generating a C1 unit in situ, which triggers the heterodiarylmethylation process. The use of inexpensive rongalite (ca. $0.03/1 g), mild reaction conditions, and gram-scale synthesis are some of the key features of this methodology.

This transition-metal-free and mild reaction offers an efficient way to synthesize aminomethylated heteroaromatic compounds with high yields and broad functional group tolerance. Here, Rongalite plays a key role in generating the C1 unit source in situ, which triggers the aminomethylation process. This approach provides a library of aminomethylated imidazo[1,2-a]pyridines and imidazo[2,1-b]- thiazoles.
