General description

2-Bromobenzaldehyde is a versatile building block used in Suzuki-Miyaura and Buchwald-Hartwig reactions, cross-coupling reactions to form carbon-carbon or carbon-heteroatom bonds

Application

Synthetic applications of 2-bromobenzaldehyde include:
  • Synthesis of aza-fused polycyclic quinolines through copper-catalyzed cascade reaction.
  • Preparation of 1-substituted indazoles by CuI-catalyzed coupling with N-aryl hydrazides.
  • It is a key starting material in the total synthesis of an anticancer agent, (-)-taxol.
  • Palladium/copper-catalyzed coupling and cyclization of terminal acetylenes derived from 2-bromobenzaldehyde and unsaturated imines can be used in the synthesis of wide range of isoquinolines, including decumbenine B.
  • Fluoren-9-ones can be synthesized by annulation of arynes, generated in situ from 2-(trimethylsilyl)aryl triflates, with 2-bromobenzaldehyde in the presence of palladium(0) catalyst.
  • It can also be used to build a variety of steroid frameworks, in which ring A is derived from 2-bromobenzaldehyde.
