Lu, Xiao published the artcileAcid-Promoted Cascade Reaction of N-(4-Chloroquinolin-3-yl)carbamates with Amines: One-Pot Assembly of Imidazo[4,5-c]quinolin-2-ones, Recommanded Product: (6-Hydroxypyridin-3-yl)boronic acid, the publication is European Journal of Organic Chemistry (2018), 2018(13), 1572-1580, database is CAplus and MEDLINE.
An acid-promoted cascade reaction of N-(4-chloroquinolin-3-yl)carbamates with amines is described. This method achieves the formation of two new C-N bonds through an intermol. amination/intramol. cyclization reaction sequence. In combination with a subsequent Suzuki coupling reaction, this three-component telescopic procedure provides rapid access to various bioactive imidazo[4,5-c]quinolin-2-one derivatives
