Abstract: This paper presents a series of six examples of 1,1-difluoro-3-aryl(heteroaryl)-1H-pyrido[1,2-c][1,3,5,2]oxadiazaborinin-9-ium-1-uides (2)—in which aryl(heteroaryl) = phenyl, 4-MeC6H4, 4-N(CH3)2C6H4, 4-NO2C6H4, 2-naphthyl, and 2-thienyl—as pyridine-based boron heterocycles with variable ligand structures. The heterocycles 2 were easily synthesized at… read more here.

DOI: 10.1139/cjc-2022-0275
Abstract: α-heteroaryl acetaldehydes have become important building blocks in the synthesis of synthetic nucleosides. Novel organocatalytic cascades have enabled the rapid generation of nucleosides, which are valuable building blocks in the development of antisense oligonucleotides or… read more here.
