Glas, Carina; Wirawan, Ricky; Bracher, Franz published their research in Synthesis in 2021. The article was titled 《A Short Approach to N -Aryl-1,2,3,4-tetrahydroisoquinolines from N -(2-Bromobenzyl)anilines via a Reductive Amination/Palladium-Catalyzed Ethoxyvinylation/Reductive N-Alkylation Sequence》.Product Details of 128071-75-0 The article contains the following contents:
N-Aryl-1,2,3,4-tetrahydroisoquinolines are obtained via a convenient and short protocol with a broad range of substituents on both aromatic rings and high functional group tolerance. Starting from readily available ortho-brominated aromatic aldehydes and primary aromatic amines, condensation of these building blocks under reductive conditions gives N-aryl 2-bromobenzylamines. The C-3/C-4-unit of the tetrahydroisoquinoline is introduced using com. available 2-ethoxyvinyl pinacolboronate under Suzuki conditions. Finally, the obtained crude ortho-ethoxyvinyl benzylamines are cyclized via an intramol. reductive amination using the combination of triethylsilane/TFA to give the desired N-aryl-1,2,3,4-tetrahydroisoquinolines. In addition to this study using 2-Bromonicotinaldehyde, there are many other studies that have used 2-Bromonicotinaldehyde(cas: 128071-75-0Product Details of 128071-75-0) was used in this study.
2-Bromonicotinaldehyde(cas: 128071-75-0) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.Product Details of 128071-75-0
