Novel synthesis of aminoacetonitriles via the selective demethylation of quaternary ammonium salts
Evgeny M. Buev,Anastasia A. Smorodina,Maxim A. Stepanov,Vladimir S. Moshkin,Vyacheslav Ya. Sosnovskikh +4 more
TL;DR: N -Methyl cyclic amines readily formed quaternary ammonium salts upon treatment with iodoacetonitrile in high yields (70-96%) as discussed by the authors, and the latter were selectively demethylated by heating in dimethylformamide to give aminoacetonitriles in moderate to good overall yields (36-69%).

A derivatization-directed three-component synthesis of fluorescent spiro [dihydropyridine-4,3ʹ-indoline]s:
TL;DR: In this article, the synthesis of spiro[chromeno[4,3-b]pyridine-7,3ʹindoline]s is achieved via three-component reactions of 5-amino-3-methylpyrazole, 4-aminocoumarin, and isatin derivatives.

Synthesis of novel benzoxaborinin-4-ones and its application in indolin-2-ones synthesis using a Suzuki–Miyaura reaction protocol
Kannan Murugan,Kannan Murugan,Murugan Chinnapattu,Murugan Chinnapattu,Fazlur-Rahman Nawaz Khan,Pravin Iyer +5 more
TL;DR: The synthesis of novel benzoxaborinin-4-one from substituted isatins and 2-acetyl phenylboronic acid is discussed and the application of these boronic acids to synthesize indolin-2-ones regioselectively using Suzuki–Miyaura reaction is demonstrated.
