Xia, Dong; Duan, Xin-Fang published their research in Chemical Communications (Cambridge, United Kingdom) in 2021. The article was titled 《Tandem vinyl radical Minisci-type annulation on pyridines: one-pot expeditious access to azaindenones》.Category: pyridine-derivatives The article contains the following contents:
A new regiospecific alkylative/alkenylative cascade annulation of pyridines e.g., I has been achieved while the corresponding classic Minisci alkylative annulation failed. This protocol provides a novel and expeditious access to azaindenones and related compounds e.g., II via cross-dehydrogenative coupling with the long-standing problem of C2/C4 regioselectivity of pyridines being well addressed. In addition to this study using Pyridin-3-ylboronic acid, there are many other studies that have used Pyridin-3-ylboronic acid(cas: 1692-25-7Category: pyridine-derivatives) was used in this study.
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Category: pyridine-derivatives
